You can press, space, up arrow and W to jump. Avoid the triangular shapes.
I give big credit to @griffpatch for creating this game. I added something new, too. So for the background, and character, I put a script that changes the color. If you have questions, please ask me. If you want to remix this, you must give credit to me and @griffpatch, and you must add something or change it. Thank you very much! To tell you, I didn't steal @griffpatch's ideas at all. ~@dayleen1233~
