The music in this game is a real jam! You've got great feedback on how well the player hit the beat, and I really like how the clouds and turning of the camera are meant to make the game a bit harder!
I came from your post asking for feedback on the difficulty. I think the input window is probably fine, but before you tweak that that what the game really needs is some visual representation of when the player needs to press a button. At least a line on each side to show where the beat is. The start of the song is manageable, but the pattern changes suddenly without warning and after the change the player has no way of knowing when they need to hit their buttons, only that they're missing inputs they don't know about. After playing a few times I can tell the inputs line up roughly with the melody of the song, but even then it was hard to hit them.
After you get some visual UI then you can really test the difficulty of the game, and it'll let you introduce new elements like holds or rapid taps!
Awesome job!

Thanks for the feedback, some of your ideas helped me out. So I've added two things to help the player out, I've added lines on each side to help the player know when to press. I've also made the wave particles change based on its state, Green for slow speed, Blue for when it is about to change speeds soon, and Red for fast speed.
