lovely prototype! Stunning pixel art and the idea of the game is brilliant!
For me personally it could've had a bit less text overall. And the very first rythm battle was quite hard. I would think of maybe some short introduction of the buttons for the lines, and some sort of very easy and slow song to get started and get a feel for it (and get me thinking I've actually earned the "you rock" :D because I absolutely sucked xD
Keep up the good work!
Thank you so much for the feedback and kind words, I really appreciate it!
I also agree to your points - this is a demo/prototype and some of the features and choices in it are not final, but demonstrative. In terms of submitting the game in time for the jam, I ran out of time to do more music and get the notes to drop in sync - the final game will indeed have different songs (the whole point will be to collect them) with varying levels of challenge as you progress! There's also going to be additional elements in the rhythm battles, where, in the final game, it will actually be possible to fail them. There are also going to be some 'relationship' mechanics with your bandmates, which will make the more challenging battles later in the game a little bit easier.
