Inspired by top-down arcade shoot 'em ups, Phase Fiends is a fast-paced action game playable in less than 10 minutes. Jump in and save the galaxy from the flesh-eating monsters. The game board is a large square and four glowing portals exist at each corner. Monsters emerge from the portals to devour the player. A timer placed on the HUD (colored numbers at the player's feet) indicates when a "boss" monster will emerge from the portals. The player must defeat the boss to close one of the portals. When all four portals are closed, the player wins the game.
