Gave it a play. The game doesn't control very well, has too weighty of a feel to it. If you're wanting platforming as a part of your core gameplay experience, you should allow for more air control unless the jumps are designed around uncontrolled jumps. But given the time you spent on it, and this being a learning experience, don't take that too harshly - also props for trying UE during a jam, most people run to Unity for quick 3D. 3/5.
