- WASD to move - Click to throw potions - Make potions by clicking the "make potion" button. - You need liquid something, eyeballs, and sugar to make a potion Press "Start" to start the wave, and throw potions at enemies to defeat them. Hearts will drop sometimes from enemies. If you have no potions, ram into the enemies; however, you will lose hearts by doing so. Try and survive for as long as possible. Comment any questions you have. This game is pretty buggy, so yeah.
