I've played some of your demo, and here's my thoughts (don't expect my constructive criticisms at the moment, I can't be assed):
Well, as far as I got the mapping was pretty good. I have no problem with your maps at all. Could you tell me where you got those tilesets from?

As for controls, by god am I disappointed with this. Even for RPG Maker, I found movement very stiff and quite hard to run away from zombies EVEN when dashing. This maybe there incidentally, but I found it a huge pain in the ass to cope with. But I I liked how you thought realistically with this, adding an energy bar for when you dash (no one can keep on dashing forever, even with a high stamina).
As far as attacking goes, I found it extremely delayed. I had to ram the 'A' button (I think it was) several times to kill one zombie. This is a pain in the ass, and I think some players would be screwed when ambushed by a horde of zombies, unless they knew what they were doing.
One thing I definitely enjoyed though, is the tension. Some aspects in this demo made me ask loads of questions like: 'What's through that door?' 'Will a zombie jump out and make me sh*t my pants?'. During the start of the Demo, I wet myself when I was walking along, minding my own business, when BAM! A zombie came out of a door and hunt me down. Good job!
The music adds to this tension, so I think you've got quite a good Horror/Survival game going on here.
Pros:-Mapping is pretty good for my standards.
-Some realism in some aspects.
-So much tension, which is what any Horror/Survival game should have.
-Very creepy music to back up this tension.
Cons:-Movement is very stiff, which can become a pain in the ass very quickly, especially when the Dash meter is null.
-Attacks are very delayed, which can lead to uncertain death.
Final Verdict: 7.5 / 10 (Y)
