I spent way too much time on the level 7 before reading the description! x) Too bad, it looked interesting (I was able to find some neat tricks in it), but indeed I eventually faced a wall!
Nice concept though! The presentation is engaging, and the music kinda made me want to play it like Crypt of the Necrodancer! :P But the puzzle are quite solid, and each one of them introduce an interesting concept and a clever challenge. The only thing it miss would be a rewind button, as it is a common feature in most sokoban-likes. But I get that it fits hardly in a jam! ^^' Overall it's a very cool entry!
