Love to see a rhythm game at a game jam, it's always great to see what others bring to the genre. I like that the story progression is tied to the player's ability and the dialogue changes according to how well you did, and I liked the cats playing in the bg and how wacky the story is. Really sets the mood.
The only issue I have is that I feel that the mapping wasn't really accommodating and it was difficult. There were times were a circle was partially on the bar and the note didn't register. Also the game immediately goes from 2 keys ->3 keys and while the 2 key map is pretty easy to play and master, the issue with three keys is that there's a lot in the UI to consider as a player and a lot of the songs have several rows of notes strung together that doesn't give the player time to respond. While it's true a lot of rhythm games do this, it's usually on the harder difficulties and I've barely gotten into the game before I'm hit with that level of difficulty.
