I gotta say, reminds me of playing fallen aces demo and fallen aces itself.. in a good way. For a prototype, the game has atmosphere and a established setting which I like, reminds of playing condemned except the whole claustrophobic areas. However, I had one problem when it comes to The goal of finding key items to unlock a door, which i think it could be improved by maybe adding a in-map flashlight that points directly at a key item. for example, one of the gangs put a flash light in one of the shelfs to remind themselves theres a key in that same shelf. Now i think about it, this seems like alot but i think its best to test it in practice.
In anyway, this game has potential and I would love to see its development in the future.
