You are a space monster trying to hatch an egg, but you are attacked by humans. Protect the egg until it hatches. Use your body as a shield if you must. Eat humans to regain health.
Ramming enemies is major strategy. Note, though, that you can take 4 hits before dying, but you need to eat 8 humans to top up your health again.
If you think the game is too easy, try skipping to the higher levels. The game stops getting more difficult after level 12.
Implemented in WebGL using my homebrew engine, and a custom shader for the background. Music made in LMMS.
