I'm really digging this. How many levels do you have planned? Also, just a little nitpick about the gore: the blood decals have to spawn on a completely flat wall for them to look right. If they spawn on a pillar or on the edge of a wall, for example, part of the decal is suspended in the air instead of being flush with the level's geometry. Will this be addressed, or is it not fixable?
Thanks buddy! The demo is only a small part of the game. I can't say how many levels there are, but the game flow will not be too short in the plan. Regarding the decals in the corner position, if the corner effect of the decals is achieved, it will spend additional graphic resources. In order to make it run well on some mid/low-end computers, this effect may not be changed, sorry for this part.
