Well I got kinda bored so I made an arena game. The knight has twice as much HP as the mage and has a short ranged 'sword swipe' attack which is slower than the mage's attack. Use arrow keys and down arrow to shoot. Press 0 to activate shield for 2.5 seconds which will make you invoulnerable for a short time. Press 9 to activate 'kill aura' where if your opponent goes close to you he or she will immediatly suffer heavy damage. Use 8 for cleave an ability where you scrafice your own lifefource (2hp for you) to do damage to your enemy (1hp). This does not need to hit your enemy, it is like voodoo. The Mage does more damage because of his fast firing long ranged projectiles but has half the health the knight has. Used the WAD keys from WASD and space to shoot. The mage has a special healing ability that will heal him by pressing 1. But make sure to be jumping or else it won't really make a difference if the knight is slashing at you. This is a 2 player game and it will be updated once it gets 10 loves and 10 favorites.
the castle is from images.google.com but other than that its all me. I keep remixing my own project so RIP ME XD
