Do I really need to say this? The floating blue thing with the eyes tells you when you start the game. Press the keys A-P to make them KILL EACH OTHER Press space to make them tell you how much health they have left, but is that even relevant? It literally says it in the top left!
I don't know who helped me with this game because I finished it like a year before I shared it XD It's not my best work, but enjoy!
