I just read some more of the other comments and learned the developer's reasoning behind no reloading and that makes sense, and also for some reason I earned the achievement of dying 50 times and still haven't earned the tiers of death related achievements yet, and also in the my review I said make some achievements I was meaning Kongregate achievements not just in-game achievements, I just wanted to clarify that.
Make some achievements, perhaps some sort of story, some variation of environments, add a clip mechanic so that you'll be forced to reload, and maybe some power-ups and that will separate it further from the multitude of zombie top-down shooters and ultimately if handled well will receive better review scores; I give it a 3/5 because lack of any elements that separate it from other shooters of the same class, other than the huge amount of skills that are able to be upgraded. I'm not saying that I did not enjoy this, because I did, I just think that in order to create this series' own identity, you need to offer just a little something else.
