This game ruled. I can't think of any other game where you can assemble your own weaponry in such an in-depth style. I really enjoyed making fire and goo bombs. Haha.
Only thing is, I got bored around 28. A lot of the enemies were repetitious, and even though the big guy was pretty awesome, it still wasn't enough. Maybe more enemies next time, and possibly background music?
All in all, I can't complain. For what this game is, it rocks. :)
