The art and the atmosphere are really well done! I love the aesthetics, the little polish where the characters would bounce around and react to you hitting the beat.
The songs sounded awesome, i loved listening to them.
The only issue i encountered was that the audio would desync from the inputs so there would be times where the gameplay would end but the song would keep going for a while.
Otherwise I loved the characters, the story, and the gameplay, well done :)
