Decent game. You should change the controls so that a double jump requires pressing W twice instead of W and then J. The difficulty is pretty low even at 7x speed. I think you should alter the game so it focuses on one speed and add elements specific to that speed. Larger gaps, more varied obstacles, and one or two added elements could make this a very respectable game! Keep at it.
Thx for your advice, I uploaded a new version that you can upgrade the speed to 20x. I tried to make it more but didn't see any point because it was way too fast. I'll work on the grafics and make more detailed games, I just wanted to see what I can do in 3 days.
