Thank you very much for your feedback!
I'm very sorry to hear the game frustrated you :( I think some aspects of the game are not clear, which I'm gonna continue working on.
Unfortunately, I don't have enough resources to test out the game, there could be a problem in how it counts beats on your device, might be some input lag, which differs greatly across devices. If you have time, I'd appreciate if you could record a video of you playing, it would help me figure out how different players play and how the game behaves. If you can't, no worries!
I wish noone frustrates over my games, I only want people to have fun as I do. I wish you a good day and I hope you get some rest after unfortunate experience, I know how a game can spoil a mood :(
Thank you for playing!
