Okay, one change I must suggest is to see if, minding the existing progression of the music, to provide empty space at the start of the rhythm boards, rather than needing to instantly hit a key as soon as the bar loops around. I think this would let the players see the bar and thus create a kind of visual guide for when to start, what tempo to follow, and thus make the process that much less stressful and frustrating. As it is, it feels like the best I can do is kind of spam the first key[s] in a sequence and hope I nail it, particularly for the faster boards.
See my other reply. Also, have you ever played a rhythm game?
Hi thank you for the feedback and suggestion :) I agree that hitting the first note is tricky and can be frustrating, especially as you have to wait the whole bar to try again if you miss it. I'm planning on changing the game, so instead of the bar moving, the notes would fall down the screen instead (like in most rhythm games, guitar hero etc...) so players should have more time to anticipate the first note. Hopefully that should address that problem.
I was thinking that might be a more elegant solution, after I had posted that earlier comment! It sounds like a fine idea, at least in theory. I hope it can be implemented easily and to your satisfaction! Thank you for the response and consideration. c:
