Overall great except a few things...
Great style, as usual, and the graphics + violence are just downright awesome. Only that the levels are way too long (and there could be something like save progress) and the intensity are a bit on a high side. I give it 9/10.
P.S. I've noticed that the brainlike stuff-spitting cactuses are counted as enemies, but I couldn't figure out a way to get them killed. Something wrong or they just can't be killed?
