TOO FUCKING HARD!!
A.)TOO DAMN HARD
B.)Needs a sex scene
I think that you should have either come up with more convincing explanations for why each level is different, or not had any explanation at all. I mean really, a weapon powerful enough to pierce a metal battle suit not being able to penetrate a cotton bra? In general, it's a good idea to keep things simpe. After all, Space Invaders never told you why you were supposed to shoot the aliens.
challenging but boring -1 rating due to it being too old u dont actually see anything enter her plus it gets annoying and repetitive
