Move with arrow keys. Sry if your mobile user. Note: I didn't put much effort in this. I just put the moving code and added the cloud. Also, I'm not sure if it works. I'm just playing with the script from @coder_d6 .
Credits to @coder_d6 for the multiplayer code. I used his/her code from the game making tools. You can look at it if you want. https://scratch.mit.edu/studios/29797825/
