My first impression about the game was quite neat - good music and very pretty illustrations. Even the plot is not that bad compared to other games about the zombie. However, the gameplay itself isn't this nice. First, the graphics - the main heroine and her animation look terrible, no anatomy, no grace (and she's said to be beautiful!). The stage music is not that bad but it completely doesn't fit - I'd rather see this kind of soundtrack in a pet simulator or kind of this.
Now, the gameplay itself - well, my main thoughts about this are that the main character is so slow that she could be a zombie as well. Also, it takes forever for her basic attack to launch and fire which can be very frustrating (however, I have an impression like there was no launch time when I was jumping... strange). In addition to this, the power spheres didn't always deal damage even when they actually hit the foe - something must be wrong with collision detection. This thing was especially annoying when I was fighting the skulls. It's like it was a matter of luck whether I hit them or not. On the other hand, it's good that the game favors some strategy. Simple running towards an enemy and shooting leads to certain death. Teleport was very useful but the ice shield doesn't seem to do much. In fact, it only slows the gameplay since I can't shoot through it as well. As for the special attack, I don't get why it's actually weaker than regular one. In most of cases using it was simple waste of magic energy. I think, it needs to become stronger to make it sensible to be called SPECIAL attack.
As for the enemies, well... no intelligence at all, but it's understandable, after all, they're zombie. However, it's quite irritating when they spawn just behind my back or... exactly in the place where I've just teleported. Furthermore, once, I had managed to hit a foe before it even became visible - that's a little bit bizarre. The bosses seem not to be more clever than the fodder. While the first one was relatively forgivable (though simple walking towards my character all the time isn't what a major threat should act like), the second guy was just stupid. What's the point of creating floating platforms on the boss stage if he can't even jump on them? This level design made an awesome opportunity for camping.
Another important thing - how do I return to the main menu? Right now, it seems, the only sensible way to do this is to kill myself three times.
I also found a few minor glitches. Once, I fell and died, then teleported and I was still alive. I wrote about some spawning issues before, so I won't repeat myself.
Overall, the game looks like a beta, not like a final product - it's playable but character slowness and spawn glitches make it frustrating. Before you make some new chapters I suggest correcting the existing ones.
