Just played through the Demo! I really enjoyed it and found the gunplay to be entertaining. The Collision for some of the objects needs to be adjusted not only for the AI but the player as well. On the Third Level the background would disappear at times may be worth looking into. The music in the Second level felt a bit off since it sounded almost medieval. I got a lot of nostalgia playing this demo and it reminded me of playing House of the Living Dead. It's a really good foundation so far and look forward to any updates in the future. I ended up enjoying it a lot and beat it with 0 deaths haha
If you want any custom music or someone just to record dialogue i'd love to help out. I'll link you my discord if you're interested.
I'll be waiting for your next update YT_GamingZoom!
