Needs a lot of work.
I rated this so low overall because the gaming is awful. It's slow and uneventful, the levels are terribly easy and the bosses are too hard, slow and repetitive. All of the human characters look exactly alike too, and your character can walk off the edge of the screen. Improve this thing resubmit it, I'm sure it can be good.
If the bosses are so slow and repetitive, then why are they so hard to beat? Oh, gotcha! SNAP!
good first try
But this could be drastically improved:
1) Takes to long to shoot and duck
2)graphics arent that good
3)WTF are the enemies?
4) the whole thing is too slow
5) cant always tell what you are supposed to be doing
focus on improving these 5 aspects for a better result. good luck :-)
