The lack of instructions at the beginning really throw you off, there's no clear visual indication on what to press and you have to spend a few minutes figuring out how everything works.
The "minigames" are sometimes buggy and they feel less responsive than they should be, in my opinion completing them doesn't feel satisfying enough to keep you hooked.
Otherwise, great music and art, the game fit the theme pretty strongly, it just need some playtesting.
