The music was weird, but I guess it was meant to match with the game trolling me. Doubtlessly your game is a liar.
The jump seemed to be glitched (or I did not get something): generally it was a normal double jump but sometimes I jumped so high that I could not even see some of the platforms below. At first I thought it depended on the platform appearance, but I could not reproduce the same results.
Hope you find the time to rate my game.
