I thought something was wrong at first because there was no backing beat to the game as the notes started coming down, it was odd to be hitting beat patterns without hearing anything. Maybe this is a bug? but it did eventually kick in.
Overall i liked the game, great job for only 1 month of experience and 2 weeks of effort for the jam. Keep it going it sounds like you got the tenacity to make more games and i know they will just keep getting better.
I also made a rhythm game for this Jam, you guys have a lot more art than I have in mine though. I think i counted only 5 rhythm games total so we are a in a tiny minority of submissions.
