It might seem difficult to kill him, but the game is coded to have a minion spawn whenever you run out of ammo on a weapon. Tricky is the main boss fight, and has thousands upon thousands of health points. The gameplay revolves around boss fights and the occasional mob fights. You punch when you don't have a gun, and fire your gun when you do.
You can also choose to use arrow keys to move and aim instead. You press A and D to move left and right, W to jump and double jump, and mouse to aim. This game is a scene by scene recreation of Madness Combat 6, which is where Hank is constantly being chased by the giant demonic form of Tricky the Clown.
