Press the right arrow to move right and the left arrow to move left. Press the up arrow to jump. Avoid red. Purple makes you jump higher. If purple doesn't work get off of it and get on again, you don't need to restart. This is not finished, I will continue to add more.
I started working on this a long time ago, and then I just stopped. But when I started playing Scratch again, I resumed working on this game. I made this game for @ikilo and my other friends who like playing platformers.
