This is a pretty solid start! I like the idea of having to plan out your moves in advance, and the mechanics seemed pretty intuitive. The main problem is the limited content, which comes with the time constraints of a game jam. If you ever decide to add to the project, I would suggest finding something to make the levels more difficult, like enemies that move around and block your path or new movement types for the player (like a jump block). Congrats on submitting to the jam!
