Really amusing little game! I really dig how the UI and such feed into the idea. I love how the intro is crash and the code in the the background is the GML that drives the game. I recognised the inputs! The comments in the code clue me in to parts of the game. I love that!
Some more useful feedback: Just two semi-major things.
1. The game mentions I should collect as many bugs as I can before the timer runs out, however I don't see a timer anywhere. So it feels as though the game just ends when it feels like it.
2. When I jump and collect a bug, and it splits, the two other parts are already so far below me that I can't catch up. Two things could fix this. Either, give me the ability to rocket back down to the floor, like a downsmash. Or, when the bugs split, the two new bugs should travel in an arc, 'popping' up into the air and away from me before falling downward again.
Having said that, I do love the aesthetic of this game! Really well done.
