Of course I tried the tutorial, but it isn't very useful during the game, apart from it's easy to make mistakes that's why you call it "unusual one-touch controls". That's why I ask you to correct that mistake, and also a basic arrow button system.
Hey! I've tested the game a while ago and I'm not sure if you got the idea of the movement. No matter where you click on the screen, it matters whether the timing is correct. When the disk moves up, if you click on the screen and hold, it will keep moving up. The same goes down. It's hard to get used to, but pretty nice to master!
