The base idea of a speedrunning game I’m totally on board. I assume the looks are a deliberate choice with the whole meth or in the description. Two things to add:
1, Please, just use free assets from people online and credit them instead of using straigh up AI stuff.
2, Harsh colors flashing inside a game can cause issue to those who are light/flash sensitive, please put a warning into your game if it features such!
12.6 seconds is what I’ve managed. Nice idea!
