Really loved the style and the pixel art. The dialogue system also is very smooth and easy to follow.
And while I am a big enjoyer of rhythm games, I can't say I enjoyed this one very much. Great aesthetics plagued by gameplay issues, having the same key regard to different lanes makes it very unintuitive and for me at least unfun. Especially in the last level that throws an entirely new key at you suddenly. The singing also doesn't feel like it matches the represented key presses, but overall the piano sounds great.
