I loved the personality of this game, from the magic sparkles on the spells to the dour faces of the blocks (until you hit them with magic to make them light up like jack-o-lanterns) to the little signs sprinkled around that just say "Hi!" to the bouncy and cheerful music. It was just so charming and cute, and that's before getting to the actual gameplay. The controls feel great and the level designs were creative and fun. I think I read on another comment that you are planning to continue working on this game after the jam ends, and I think you have tons of potential for new mechanics and level gimmicks to play with. Overall this was a really solid game that I enjoyed playing!
By the way, we played your game on our stream tonight!
