Very cool but the WASD keys do not work on Firefox. Arrow keys work fine though!

edit: it suddenly started working after I switched to a different tab, and then back to the raycast's tab.

I have zero experience in graphic design, but I do not think the simulation is made for designers.

Very cool, but please change the color selector. It is not intuitive, and it's very hard to pick even the most obvious colors.

Yeap, at least I got a refund.

Besides Stripe and Braintree, I would like to recommend FastSpring. Accepts credits cards, Paypal, Amazon and others. Supports recurring payments (perfect for SaaS) and single payments for products. Has great support, and the fees are very low. I have been using them for more than 2 years, and have had no issues.
