LevelNumb

I liked it better than Claptrapino. Maybe because I'm a novice level maker too. Obviously it's the work of a newbie, but I absolutely understand how it might have taken 10+ hours. I think I've spent at least that long and haven't even completed any levels yet.

I actually thought it was an interesting basic concept to start in the middle of a maze, with areas you've previously cleared not guaranteed to be safe anymore with the portals and spawns. I died twice in my attempts and finished the third time. When I realized that staying in place, conserving resources and clearing wasn't working I took the invulnerability and just ran through the halls spraying high damage weapons.

The level did seem unfinished though. What are the keys for? Are there secrets in the level that contain locked doors?

I felt playing another terry wad, but worse.

You should work with textures and the idea of it, not just placing spectres everywhere with a trigger action to spawn a cyberdemon.

EDIT: Why you been working on this map for 10 Hours?

That's actual looks like a 15 minute made map.
