This is a very simple platformer base. You can copy the script for your games. 1.0: Right and left arrow keys move you right and left, and the up arrow makes you jump. Red kills you, green is ground and yellow is the end of the level. In addition, you can climb up brown. 1.1: Now you cannot go through brown and you bounce off it too. Press e to change the cat to a square. STILL HAS A BUG WITH THE BOUNCING OFF BROWN WHEN GOING RIGHT!! I need to fix it. 1.2: Slowed down right and left movement.
