I love the idea of a rhythm game! The songs that you've made for it aren't half bad. I'm actually a big fan of rhythm games, so it was nice to see. There were a few things I did have a little bit of a problem with, however...
The sound effects for characters talking tended to be a little bit on the grating side. I didn't want them to finish their sentences, because their sound effects in talking were a bit grating for random pitches.
Another thing is, I'm not sure if my game was lagging at all, but when I was playing, the notes didn't really correlate to what the music was playing. I'd be down with either more difficulty by matching it closer to what the cat was playing, or choosing the main notes to hit that would simplify it, as it didn't really feel like the notes were too much on time, or relevent to what was actually happening to the music. The last song ended up having a few extra notes at the end when the song finished, so that's why I was assuming lag had a little bit to do with this.
I would like to restate this, I love this idea, and I think a little bit more touching up would honestly be one of my favorite games in the game jam.
