A nice game, simple, good looking graphics and visuals, and an interesting principle to differentiate it from most of puzzle games. The only slight issues I had were: 1. the music, as it got repetitive pretty quickly, but I understand that good free-to-use music is hard to come by, and 2. the world design, as some hitboxes are illogical (for example a snowman is standing in a corner of a square and the whole square is blocked out), but since it doesn't deny me from completing and enjoying the game, I don't mind it.
TLDR: Nice game, great job devs.
