Great concept, especially for a demo! The design of the mannequins is creepy as hell, but the game design seems to be a bit lacking. For example, the gun and first note weren't made immediately noticeable, unlike the second door passcode, the inconsistency of which threw me off a bit. Something else that drew out the immersion a bit was that alongside the pistol, there were also assault rifles in the security area on shelves (which the player was unable to pick up). As for bugs, I noticed that the first mobile mannequin doesn't move until you pick up the gun, resulting in a perpetual idle animation (which in my opinion is much creepier than the running animation). Also, the gun was able to be reloaded without shooting first, and infinite magazines were made available. An idea to consider in order to increase the tension would be to have limited magazines for the gun, causing the player to have to make decisions as to whether or not they should reload and lose precious ammo or keep what they have and risk running out in a fight. Overall, I look forward to the finished product.
