Gave up on level 13! I think it speaks to how well designed this game is that I played for that long, I am not normally a sokoban kinda guy but this was great. Incredibly clever puzzles that teach the player the mechanics beautifully- that one level where you teach the player that boxes can push other boxes and then use that in the next puzzle on that screen? Immaculate. My only piece of constructive criticism is that this game could really use an undo button. But it's a game jam game, so fair enough! Excellent work, this is my favorite game I've played so far this jam!
