I also made an asteroids inspired game. I really feel for you on the 7.5 hours of bug fixing. Good job grinding through it though. Even if you didn't get something working in the end I bet you learned some stuff.
Made this in 9h 5min total. (Game is broken)
Idea was to make asteroids inspired game with some twists.
Tried adding sfx at like the 10 last minute that made it crash so that's why I went over a few minutes (and didn't even get sfx to play).
I had so unbelievable amount of problems. I thought it would be a good idea to work in Typescript + Babylon js since I have done that a lot lately. But I probably spent like 7.5h fixing errors and bugs. So next time I'll use Unity unless I make my own game engine for typescript.
