Alien survival! [Alpha]

You crash landed on a hostile planet filled with aliens! How long can you survive? ENEMIES: Alien: They will simply follow and kill you. UFO: It will follow you and try to beam you up. You can escape them by climbing onto a ship or tree. NEW ENEMY: Sticky Alien: This alien will attach to you and steal your health. To get rid of it just shoot it till it dies. It will respawn every minute, and it can fly through walls. I'd say this is the most annoying enemy. NOTE: If you kill a UFO while in it's beam, you'll be stuck in the air forever. To fix this, just reset. I will fix this in a later update :/
