Hello!
Some things about your map... the layout is very basic, but the map is way too small. I know a thing or two about small maps, seeing as how everyone I've made is to small haha.
Also, the textures are basic. There's only one throughout the whole map.
I suggest adding onto the map and making the corridors much bigger. Otherwise, I'd say the map is only fit for 2 people.
Anyway, it's still nice. Basic and simple. :)
