Cool little puzzle game with a lot more levels than I expected! The concept is simple, but you managed to add your own touch with some clever mechanics, like the rolling & bouncing boulders, that makes the puzzles very unique and enjoyable =).
The graphics are cute, the music is fitting and you really took the time to implement a lot of audio feedback, something often neglected in jam, so great job ^^! The theme is here, even if it's just "cosmetic" (you could replace the doors by anything and it would still work fine), so overall, that's a solid entry, congratulations ^^!
