Great music! Credits were a bit of a jump scare, I had been switching back and forth between tabs to see when I finally slowed down enough to skip the fall. On that note, it may be better to have skip appear [10? 15? some number] of seconds after launching rather than waiting until velocity is below 0. Takes a good while to get to that point when your last launch will be seeing some 16k velocity and the only thing slowing you down is gravity with the last steel cap upgrade!
It felt like springs were a bit stronger than they should be, and the CRT effect was a bit harsh on the eyes, but otherwise it was a nice experience. Hope ya had fun making it, and keep at it!
