Really really great game and concept! The style is nice and the idea of using different colored-stones to guide you, although not uncommon, was well-executed imo. The controls took some getting used to since it's isometric tho. Also, I suggest a restart button since it's common for puzzle games and I got stuck in one puzzle and couldn't move.. The sfx and music is fitting too, along with the simple art, which could be more polished but it's nice enough to look at. Great game overall.
