Well-made but not especially fun
The graphics are nice, the animations look good, there's a nice shotgun sound, the music fits well, and it's a good idea over all, but the game play leaves a lot to be desired. For the first level, all you do is shoot, then duck, then shoot, then duck, over and over. The sheer predictability of it makes the enemies too easy. But then you get to the first boss, who is WAY too difficult (in my opinion). Dodging his lasers is easy, but you can't seem to avoid being stomped on. I died without leaving so much as a scratch on him, and frankly, the game play is boring enough that I don't feel like getting back up to him to try again.
You, on the other hand, SHOULD try again, because with a little more effort and playtesting, this could be a fun game!
