So for general bugs I've noticed on a few "buildings" primarily the three at the far left of the upper area, you can walk into the side and get the player stuck, but still back up to free oneself. and the section located below spawn near the right entrance of the "hallway" that you stated does not go transparent when the player walks behind it also stops the player from being able to move left or right on occasion. another spot that causes players to get kind of stuck is down the right hallway, the lower walls in the lower "hallway" can cause the player to get stuck. feel like I should mention this is done by holding down the movement key into the surface and then pressing another key to strafe across the wall while moving into it.
I'm not sure if this is a bug but the AI can be used to shoot other AIs and kill them. so strafing and running around them to get them to kill themselves apears to be the best way to kill them.
Other than that game appears to be stable. Did notice windows firewall does not want to allow game to launch but gave permission anyway and this caused no further problems. looking forward to seeing what you do with this!
