Really liked the later levels, where you had to time your deaths correctly. Also, big props for including stuff like level select and sound volume options - rare to see them in a jam game!
My only real complaint that haven't been already mentioned is that the movement (esp. jumping) felt a bit unresponsive. I really recomend checking out the coyote time trick somewhere on the internet (I believe that Jonas even has a video on this topic on his channel) and to use it every time you're implementing a platform movement.
Really creative entry compared to the other similar entries on this jam. Good job! :)
