It's actually 3 towers + 6 second versions of them + 6 third versions of them. On top of it 3 spells, and about 27 ways of updating your stats. 15 different stages and +- 10 enemies. Flamezombie - your opinion lacks any experience in playing this game. It would be nice to stop being childish and see how much work it needs to do that kind of flash game.
Nice game but really anticlimactic. Good plot have to put you in position you wanna find answers. But this one doesn't even leave any questions you would care for. They came to this planet, wander a little around, found some weird stuff, yet nothing too weird happened to them, so they left. Yet graphics are amazing. Game's a beauty. ;) 4/5
