Rhythm games work real well for jams and I'm unsure why they aren't done often, maybe it's because it's sometimes difficult to match the gameplay up with the music. In this case it turned out really well, I didn't experience any jitters or out of time inputs so great job there! In terms of variety, it would have been nice to hear a couple extra tracks in there but I imagine it was difficult with the jam's timeframe. Either way, great job on this, I enjoyed it!
