WASD to move. Click on nearby monsters to attack. Your goal is to find a huge ruby hidden in the labyrinths, said to have magical powers. Potions wait until you have zero health, then restore it to full. If you grab multiple potions without using any of them, when you do use one, it uses all of them.
THIS IS A DEMO. There are still things to be added, such as making monsters collide with walls. For the credits, @griffpatch for an idea on how to make sprites scroll off screen.
