Quite. I had a great Christmas break a couple years back going through all the missions. It has some edges to it but people have also implemented things like RISC-V in it so it's also quite complete. The game portion is enough for fun and exploration.

I got all the way to the final missions where you're writing your own assembly (that you created) to solve various programming puzzles. Only stopped because I got busy with something else and break was over. I def recommend it. Reminded me at the time of Code by Charles Petzold but applied.

(Last I checked the Author was rewriting much of it for performance reasons and to fix up a few gotchas that should be possible with circuits but aren't here - no idea if they still are but that was my understanding before)
