Arrow keys to do the movements. Just press the arrow that matches the one going up (the one with the smiley face) and do it when it touches the identical arrow (without the smiley face). You'll get different ranks for how well you do. There is no dying in this game. Im sorry that the ranks can be weird and not right. There are still a few problems with the rank thing, so keep that in mind if you do really good, but instead get a really bad rank.
Inspired by FNF. Result music from Cuphead. Super Smash Bros. Ultimate for the sounds for the messages that say, "Warm Up!" And "Start!". Geometry Dash for the song used during gameplay (The song for Limbo (Isolation)). Undertale for the second warmup sound effect. I have no idea if it's possible to get an S in this track I left a little surprise for you in the background's code for when you see inside...
