Has anyone found any of the other doors? I have gotten clear to the ground floor and I have no idea where else to look ???

I am currently playing this map and it is pretty fun. However, there are a couple of things that I would like to address. First, the box. Buildable box? Super freaking cool! however, it would definitely be a lot more interesting if you could actually use it. Right now you cannot and for me as a starting youtuber that made me rage a little bit. Second are the weapons themselves. Guns are great. However, there are two problems with them. First, the wall models stick out of the wall and you can get stuck on them and go down. Second is the description. All you see are question marks. There are no prices and/or gun names which made the game a little more exciting but not necessarily in a good way. Other than that the map is really cool. Lighting is pretty good other than a few very fixable texture problems and the problems mentioned above that map looks great! It definitely has potential to be very good
