This game is one of my personal favourites in this jam! It's so fun and, once you get how the game works, has the right amount of challenge! I hope you work on it to expand the number of instruments, people, and fakebook entries!
As some others have pointed out, shooting notes is sometimes unresponsive, and that can give a lot of troubles. Also, I can't slide with the guitar!
Oh, a major bug I found: the notes on the underside take a LOT of time to appear, which is kind of a bummer (although I'd love a no-note input mode as a hard difficulty). However, if you wait enough without starting to run, the notes begin to spawn anyways!
