Nice defense game. The graphics are great in this, I love the drawings for the cutscene especially, all very detailed and well-worked. The game itself is a combination of simple concept/control, and waves that get tougher and tougher, though it's a bit annoying how long the gun takes to reload at the start. Would also be nice with some kind of crosshair. Otherwise, great work!

Like most peeps are sayin', the game IS pretty hard and frustrating. But the concept is downright cool. ;) The graphics are OK . Not the best graphics for a 2D game, but it's OK. The narrative in the beginning is pretty nice. Music is nice and fits the game perfectly. Overall, I'll give you 3.5 stars. :)
A little to hard, i made it to level 7 then said "Screw it, kill me." But other then then the difficulty the game is great.
Very fun game. A little more depth, in terms of upgrades, enemies/ bosses, and guns, you'll have yourself an excellent game.
....but...the oxygen would just fly into space.... the moon's gravitational pull isn't strong enough to support an atmosphere....not to mention you need more than just oxygen.....and even young plants produce oxygen....you could even use cyanobacteria....or algae....also *smack*
