"Your final time is 11 : 37."
I had a lot of fun playing the game.
Switching to full screen should definitely keep the original ratio as currently you can't really use it and need to zoom in your browser instead. Despite the jump feeling very weird even if couldn't give the exact reason the game is still pretty fun because the level design is very good with the multiple paths through levels, enemies which are fun to deal and the occasional power-ups and the proposed difficulty is right on point.
