I found it fun, even though it is very small and the brushwork is very plain and ''cubish''.

Very weak. Small, arbitrary, uninspired. Contains both silver and gold keys, but neither of them is used for anything. At one point, I couldn't get down a lift to fight a shambler because we was standing underneath it trying to get at me. 1/5.

Really poor work. Corner "teleports" are strange, they're like water and you can lift up swimming in it.

That is not how you spell tightrope. It is how you spell a boring, ugly, confusing and short level though. Not recommended at all.

Ugly and bland visuals. The map is very short but also very confusing to navigate due to all the false walls. The combat is not difficult at all. This level is rather terrible, avoid it I say. 1/5

I echo everyones comments above. The map is basically ping ponging you from one room, to another but there are only 3 rooms! I do think you need to get both keys for the exit to show, but Mike above is correct in that I don't know that either are actually used to open anything in the proper sense, like when you walk up to a door. It's an ok map.

What is with the beginning area and the opening/closing walls? And the green armor? I could never figure out the right pattern to get to that.

I found the opening and closing doors at the beginning an interesting enough quirk to warrant this map a 2/5 from me.
