I don't think this is my style of game. The tank controls were a little strange to get used to and the rooms were a little too mazelike, in that it was hard to keep a mental map. That's the point of a maze - I get that - but I'd hope there's room for design in a full release to help the player navigate more easily.
Congrats on busting this out in two weeks! There seems to be a good amount here and it looks really nice and fleshed out. I imagine that's a lot tougher in a 3rd person 3d game. The music was just unnerving enough to make me not want to play a second time to try to finish lol. Not my kind of game :)
Good job and well done!
