Description: Defend outer space from enemy spaceships. This is an simple tower defence game. You know the drill: buy and advance towers, kill enemies, get to the finish. The game gets progressively heavier, and there are a hundred levels. **Note** It bugs sometimes when the game is over. If it does not go to the high scores page after the game ends, right-click and click Forward (you are able to do this at any point in the game if you want to submit your score without finishing.)
