I must admit this game is very polished, the art style is very consistent and the music with some effects are made almost perfectly (especially for each instrument which starts to play when the jammy is fit well). This game seems to be free from any bugs, but I have two issues which could be considered to be resolved, the break between “stages” is a bit too long or could be skipped by key. The second, the time needed to complete a level could be more balanced: for harder one, switching between jammy (color) variants takes a lot of time and (also) I was unable to finish the last stages due to lack of time.
