Dude I collected 150 coins but I only able to do one upgrade, now I feel dumb :D, It was cool game. And upgrading engine is a bad idea cuz I got jump scared by an enemy with high speed. My max depth is 1200m
thx, the upgrade system is a bit broken, I agree. :D I see a jump scare by a cute red blob as a win in game design. :D 1200m is also very good, congrats. :)
