Move with arrow keys. Throw stuff with space. Throw food at others before they do so to you.
There are many bugs to fix. 1. Sometimes food floats in the air 2. Some scripts don't stop even when I told them to stop 3. Sometimes the opponents are invisible There were more but I forgot. The player is too invincible, also. Maybe the transitions between levels will be smoother in the future. It would also be great to have a thumbnail and a death screen.
