Arrow keys, wasd, or mobile controls. You can use this to make a cloud multiplayer platformer, but you can't backpack it, you can only remix it because if you backpack it the cloud variables would only turn into the variable but with a cloud emoji. I am not kidding you. This has 10 levels you can make. If you want more, you can change it.
Might add chat soon!!!!!! (Whitelisted) This is a Cloud multiplayer platformer engine. With this, you can play with other people online using the cloud. Although since new scratchers don't have access to cloud variables so if you are a new scratcher unfortunatly it won't work. This does have wall jumping, so you can add that.
