First of all, you did a good job on visuals and concept. I like rhythm games and this one is alright considering it was made for a jam. The gameplay felt a bit frustrating however... the lack of interesting breaks in the songs, and on some customers the gameplay would start but no actual impactful music until a few seconds later. (little things like that make the rhythm part feel less interesting and more like random button prompts)
Anyways, I thought the music and art direction were still quite good and polished, and just wish I enjoyed the gameplay more to keep playing. Overall, good work, hope you guys continue to make games.
