GlueFO

Tired of the same old Asteroids clone? Try GlueFO instead. This neat little take on the arcade classic has you firing the smaller asteroids at the larger ones in an attempt to break them up, but watch out for the enemy GlueFOs that turn up in later levels, as they have other ideas. The game tutorial is literally 45 seconds long, and with two game modes (simple and advanced) there is more than enough options available to dive straight in to the addictive little game.

Once you've mastered the simple version (and fallen in love with the fantastic background music) you can go try to see what sort of score you can rack up in the advanced one which has a combo and speed scoring system.
