Wow! Just wow. Beautiful map. Lots of attention to detail. Very good framerate. Amazing lighting.
Despite that, I just wish it had some quest or ee. The map is quite large and too easy. Because its easy, there are limited wonder weapons. There are no boss, only dogs. You can practically camp until wave 30 easily. Once you pap, gameplay could be doozy.
Anyway, in terms of visual, I would ranked it among Clinic of Evil, Leviathan, Das Harrenhous.
