This is half of the multiplayer game, MeshCube. You must first activate Mesh http://scratch.mit.edu/forums/viewtopic.php?id=32046 in Scratch. Then, download this project and have a friend download this other project--> http://scratch.mit.edu/projects/7scratch7/1804551 and click the green flag on player 1's game! Both computers must have Mesh activated, and they must be on the same local area network. (basically, in the same house) You control the red square. Move and jump with the arrow keys. Your goal is to not fall off the screen! The game will start when both players jump up. Tip: If you want practice, play on MeshCube 1.
