great demo really like what i see so far.
combat feels fast and intense and forces me to be on my feet which is good.
how ever i would say my biggest complaint would be the enemys with guns shooting your character as soon as you round the door. mostly when your model is exposed the seem to hone in and fire away.
perhaps a way to fix this is let players take some of the injured folk as a meat shield and use them to block the bullets for you allowing you a chance to hit them first. (its frustrating to get shot by something you couldnt see) this will also reward players to maim their enemys instead of just killing. i also find that enemys can quickly overwhelm the player quickly. this could perhaps be fixed bu alowing the player to block with their fist ( to take reduced dmg ofc)
i find that some of the enemys are able to survie a head shot which i fel is a bug.
otherwise a good game demo that shows much promise i cant wait to see what you make next
