Lovely entry.
I love the implementation of the theme. I also had that restart bug when I jump at the start, but in the second level it went away. Looks good and challenging. Only suggesting I'd add is maybe binding the left/right switch of E to specific buttons, so it would allow you to switch mid-actions, and not stop your action to switch the state - that can unlock many more options for the player (and also many more challenges!)
Well done :)
