Tulez Run

Even if you get a Game Over, you can still press the Space Bar to jump. From there, you can very easily get a ton of points. Also, the running animation seems awkward, and the red spikes move too slowly. You should add other obstacles to this game other than just spikes.

The bottom line is that there are multiple bugs in this game.

Fix jumping, l can get points by just pressing space on game over and maybe you should make it so when you truly avoid the spikes you gain points, not by just jumping
