For my standards the concept of the random jump is bit unoriginal, but it fits theme nicely and with bit of training I can see how one can have fun with this game.
Personally I would make the jump activate with up arrow and it was also bit confusing to go on even though.
Even though the jump is random, you can still move around rather well, witch for me is a plus and I like the slite of Baba Is You vibe the art has.
Owerall it's really nice game jam entry.
