The art very cute and the premise is fun. Most of the minigame itself is interesting, but the dance dance revolution one is wayyyy to strict, miss a step and you fail immediately. In addition, despite being a musical-themed, it lack a lots of SFX to add the juice to the game. And the music is too gentle for this kind of concert, lack the oomph of what a end-of-world concert can be. I think the last 2 points if fixed would make the game very enjoyable. Good work!
