Nice idea, and puzzles are actually well designed! Obviously there's a lot to explore and develop upon.
In a game like that it's absolutely neccessary to limit what player can do so they doesn't fail themselves. In a scope of a game jam, I would recommend making 2-3 rooms with well-tested physics over 10 rooms that breaks anyway. And of course once you tested, if there's still time, you can add more levels!
Jump height and run speed felt unnecessary high for a puzzle game. But overall, I enjoyed solving puzzles.
I wish you good luck in your future works!
