I'm a big fan of puzzle platformers, and this one seems like it could be a great mechanic for one. It just needs a little bit more polishing for the assets, but the core idea works great! One little thing I would fix is I would add a coyote timer for the jumps, so that it's not so hard, specially when there are levels which the jump distance is almost the maximum possible jump one can make. Overall good game, congrats!
