Concept: cool, I like the minigame aproach.
Gameplay: the minigames are fun. I did find them a bit too short though. Maybe a few more minigames could spice it up, though I know how hard it is to get even a single one functional with this time limit so it's fine.
Art: it's nice. Gives big mobile game vibes with the large sprites and the skeleton hand pointing.
Audio: pretty good, fits all round.
Overall pretty good game with good polish.
