Deleting the A input on frame 17,252 causes the game to lag, despite the input being seemingly meaningless.
I spent about 6 weeks optimizing the star room in Bubbly Clouds and I hope I never have to look at it again.
There's a way to save one frame during the fight but I can't get the ending to work as well as it does here.
used the japanese 1.0 version of the game. i really want to see a new tas of the game so just in case someone needs this
