Left and right to move. Space to shoot; your attacks are homing. Defeat Henry the Anglerfish (now severely nerfed) You have 3 HP but that replenishes every new phase. Herny has 1500 HP. A new phase will begin after you have depleted 500 of Henry's HP. All of Henry's attacks are nerfed.
I apologize for the awful platformer controls, I simply couldn't be bothered to "borrow" my platformer code from some random griffpatch over there. Scroll down Instructions to see more details and Henry's attacks. Background music is Midnight Fortress by DiroNomer and the rest of the sound effects are from The Battle Cats by PONOS Corporation. The idea of naming the anglerfish Henry was also by PONOS. Enjoy!
