Operation Lyfus

Operation Lyfus - Very addictive game. Easy to play, just 2 keys (ship does auto-fire). Avoid collisions with asteroids and other enemies and direct the ship's fire to explode them.

The game has 4 levels:

1. Asteroids: Just asteroids... Avoid them!
2. Chase: The enemies ships will try to chase you.
3. Fireback: Ups, they will fire on you. Destroy all of them.
4. Infinity: Big, big level. It will take you a lot of time to complete, but if you are a master you will finish it.
