Show HN: Bubbles, a vanilla JavaScript web game

[ehmorris]

Hey everybody, you might remember my older game, Lander! It made a big splash on Hacker News about 2 years ago. I'm still enjoying writing games with no dependencies. I've been working on Bubbles for about 6 months and would love to see your scores.

If you like it, you can build your own levels with my builder tool: https://ehmorris.com/bubbles/builder/ and share the levels here or via Github.

[SamBam]

Nice.

It took me a few times to realize that I could do bombs or slingshots by clicking in empty space. The tutorial makes it look like you have to click on a bubble. Maybe the black circle in the tutorial should be removed?

I also got a little confused in the beginning about par vs lives. At first it seemed like par was the only important thing, since that's what pops up after the level. The lives icon at the bottom wasn't particularly noticeable to me. I just kind of figured there were only N levels, until I finally realized that dropping bubbles was making me lose lives.

Edit: Oh, and you can multi-touch and set off multiple slingshots at once! Secrets secrets...

[a1r]

This. The 'black circle' in the tutorial is no good, maybe a dotted circle instead to make it clear you're supposed to be tapping empty space and not a black bubble.

[megadata]

I had exactly the same experience.

[stevage]

Really well built, and I love the tutorial...

BUT

Jeepers, it starts off so hard compared to the tutorial.

1. I was not expecting bubbles to move (since they are all static in the tutorial).

2. I wasn't expecting a golf/par scoring thing.

3. I didn't realise you could (and should) start powering up during the countdown at the start.

4. Took me a long time to realise you can just click quickly to create bubbles, without having to do the aim-and-shoot thing.

5. Straight away I felt like I was being insulted by having my score described as "Disaster" etc.

6. There's no way to get back to the tutorial.

So overall, I'd say:

- there are fun mechanics here

- it's good there is a tutorial

- but the tutorial did not prepare me for the game

- the game felt too hard too quickly and mean

[BizarroLand]

One more kibitz, each level should give you the option to replay at the end so you can hone your skills, and only your best score should carry over.

[megadata]

Slick as silk! But too fast too quickly. Gimme some easy endorphin in the first few levels before I start struggling.

[t0k0l0sh]

Agreed, perhaps it's easier on a mobile device but I found the first two levels after the tutorial way to fast using a touchpad and left a little frustrated :-(

Easing into the difficulty slower sounds like a good plan!

[mjburgess]

A touchpad seems to really cripple the gameplay -- one idea could be to ask what device players are using and make slight adjustments. For touchpads, moving the cursor is slower, and the drag-pull mechanism doesnt really work -- and its easy to misclick a drag.

Some rougelike mechanics would also make it possible to naturally level the gameplay -- ie., the more failures a person has the more metaprogression they get, so worse players unlock a natural easy mode.

[flanbiscuit]

> and the drag-pull mechanism doesnt really work

Doesn't work for me at all on both Firefox and Chrome (latest versions for both) on MacOS using the touch pad. I can't get past that screen on my laptop. Had to open it up on my phone to see what comes after.

Otherwise it's a fun challenging game

[dylan604]

I walked through the demo thinking that was a decent demo. Then round 1 and nothing was the same.

I was playing with a magic touch mouse, and have decided it was not designed for that interaction. Assuming designed for mobile and us desktop users are just square pegging a round hole.

[ehmorris]

Yes desktop is extra challenging. On mobile you can spam slingshots with all 10 fingers but on desktop you’ve got to be leet fast.

[putzdown]

Yes, as other commenters have said, this game is a great example of the design error where the tutorial careful prepares the player for not-this-game. There’s another game out there somewhere that the tutorial has made us competent to play. Meanwhile we need a different tutorial for this game.

[ricardobeat]

Really nice interactions. A bit too fast paced for my iPhone Mini, and I have no idea what this “par” and “bogey” stuff means (is it golf lingo?), but looks promising!

[blinding-streak]

The tutorial has zero in common with the actual gameplay. Why would you do that? It's not a good onboarding experience. It just creates frustration.

[simpaticoder]

Really cool stuff, ehmorris. Your work harkens back to the early days of the web when bundlers and minifiers were the exception, rather than the rule. Work like this can really help beginners understand how powerful vanilla JavaScript can be by just looking at your source!

One neat thing you can do is embed an SVG favicon in your html page, which will be properly rendered at all resolutions on all major browsers - plus it saves another sub-resource request. Here is the favicon at https://simpatico.io/svg

  <link id="favicon" rel="icon" type="image/svg+xml" href="data:image/svg+xml,
  <svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 1 1'>
      <rect width='1' height='1' fill='DodgerBlue' />
  </svg>"/>

This can help you make your already clean source even cleaner and delete some subresources. Cheers!

[herczegzsolt]

Way too hard for me to be enjoyable.

[IshKebab]

Yeah it's kind of laggy too.

[zakki]

In my phone, Samsung A14 5G, I have to touch screen below falling bubble to blow it. If I touch the exact location, it is too late.

[ehmorris]

Oh no. That will make the whole game frustrating. I actually recently made a change to try to mitigate this so I’m sad to hear it’s still an issue. I take the pointer position on pointerdown and pointerup, and do collision detection both times. Then I pop the underlying bubble in either case, giving you the benefit of the two possible pop locations.

[simbas]

Same on pixel 6a

[thih9]

Cool!

Feedback: the concept of “lives” spoils the fun for me; I’d like to retry a level without having to replay earlier ones.

[TZubiri]

In desktop, dragging outside of the square canvas (and of course outside the windows) doesn't quite work.

I wonder how you would fix this, I think you could "capture" the cursor, and use esc to return it, not sure if that works in the browser.

[RomanPushkin]

(shameless plug) Another JavaScript you might like https://make210.com/ (I'm the author). Do "Restart -> Hard" for a challenge.

[fyrn_]

I want to be able to replay a level, don't force me into the next level.

[neogodless]

I really don't understand the 4th level. Is it much easier on a touch screen? With a mouse I can't seem to intuitively set off a rocket or whatever that can get the cascading falling balls!

[ehmorris]

Oh, this one is one of my favorites. If you time it right, you can get all six with a slingshot of the right speed.

[90s_dev]

Your source is nice and clean[1]. No dependencies is a wonderful goal. Status quo is inherently always against innovation. I like the approach the Go team took of rethinking new solutions from first principles, and I hope you got to experience the joy of that in this project.

[ehmorris]

Thanks! Writing the game has been really fun and I’m proud of the codebase. It’s therapeutic to work on it because I get to skip all the frustrating parts of web dev like writing config files.

[redbell]

A pleasant game, love it! Also, the name Bubbles reminds me of: https://news.ycombinator.com/item?id=33566924

Another fun game from the same author: https://news.ycombinator.com/item?id=35032506

[Minor49er]

Kind of makes me think of the trip-out sequence you get on https://packardbell95.com/fortune/ after you drink the soda, if you pop all of the carbonation bubbles on the page by clicking on them, you get made fun of in a pop-up for wasting your time

[boutell]

Looks neat... can't drag the ball in linux chrome (dragging works for me elsewhere), maybe I'll try later on my phone.

[ehmorris]

You've gotta move your mouse at least 36 pixels within the first ~200 ms. You might be pulling it too slowly.

[PonyoSunshine]

Same problem for me. MacOS/Firefox.

[colecut]

same problem on macOS chrome

[EspadaV9]

Fun little game. As others have said, the tutorial is nice, but very misleading compared to the actual game, and the game starts way too hard.

I beat Bubbles! 1951 over par overall

https://ehmorris.com/bubbles

Tapped 90 times: 0 hits, 90 misses Launched 2202 slingshots Detonated 1 blast

[gjohnhazel]

Love this game! Took me quite a few tries to get through levels 15 & 16. But when I finally did, I was only 1 over par! 3 missed taps, 77 launched slingshots, 13 detonated blasts.

[hakaneskici]

Your code is such a fresh air after being subject to a decade of bloat. Thanks.

[sysashi]

Cool game! at first I thought it's an "aim trainer" of some sorts :D I forgot about everything (slings and bombs) besides clicking and tried to click all the way through.

[EstanislaoStan]

I beat Bubbles! 368 over par overall

https://ehmorris.com/bubbles

Tapped 8 times: 2 hits, 6 misses Launched 444 slingshots Detonated 55 blasts

[ehmorris]

A slingshot tank! Did you like the fireworks?

[nightpool]

Fun game! Getting some errors trying to set the velocity of balls: https://i.imgur.com/fXOJ7UT.png

[daniel_iversen]

Wow, incredible work! It seems quite novel to me and was super fast to learn and instantly fun to play! Did you consider wrapping it in a mobile mobile app to try and make a few bucks?

[ehmorris]

This is my “finally try to make something real with AI” project that I have yet to do. I have no native experience. Both for this and ehmorris.com/lander.

[gjohnhazel]

Also please add more levels and I’ll enjoy even more! I do think this could easily make some decent money as a mobile app.

[ehmorris]

I’m glad you like it! Anyone can use the builder and submit a level suggestion through github:

https://ehmorris.com/bubbles/builder/

[owebmaster]

Beautiful JS code, happy to see this after people started to create DOOM using TypeScript types.

Edit: yay, beat all levels after learning I can use slingshot multiple times

[latexr]

Having to restart over and over kills it for me. I’d much rather be able to repeat a level until I got it perfect then move on.

[jsherwani]

it would be nice if i could save my progress at every level so i could just keep working on one level at a time.

[wkirby]

Absolutely love the sound design on this.

[ehmorris]

Me too. They’re all by my friend Max Kotelchuck. He made the sounds for /lander too.

[tobyhinloopen]

Way too fast to start with. Is it design for phones? Because on desktop it is moving way too fast

[bosky101]

Great onboarding. Super smooth. Why isn't there a try again even if you succeed. Congrats

[bhavik_dand]

Cool game. Tutorial is easy, but difficult to progress.

[vivzkestrel]

so what are those bubbles? divs with a border-radius of 50% that transform X and Y with random values? how is this implemented?

[ehmorris]

Everything is drawn directly to canvas including the score view:

https://github.com/ehmorris/bubbles/blob/de0c6c8b40328df9fcf...

https://github.com/ehmorris/bubbles/blob/main/scoreDisplay.j...

[anentropic]

too hard

and when trying to do a slingshot it's easy for the mouse to go outside the app and then the shot gets stuck without firing

[jeffd]

Pretty slick experience from Mobile Safari!

[bryzaguy]

This game is so good! Played on my iPhone

[hyperfuturism]

beat the game with 31 over par overall. im on an iphone 16 pro.

touchscreen users have huge edge over desktop for sure.

[higgins]

Good old fashioned addiction

[jrks11o]

input delay heavy on mobile browser, otherwise nice!

[ehmorris]

Ah bummer. Some phones struggle because the bubbles are pre-generated bitmaps drawn each frame.
