I loved the blurry effect and the geometric platformer style. Very good.
I found interesting the idea of controlling two players, but it would have been good to explore this mechanic to solve the levels (like adding the possibility to jump on the top of the other player). Maybe some suggestion if you plan to work again on this after the jam would be to adjust the movements a bit (the left-right feels very fast, while the jump is really slow) and the hitboxes (when you collide with a platform, you can see the box entering a bit into it before being shifted back).
Anyway, nice job! :)
