Answer 1

tubular

Answer 2

The open bit at the top is such a red herring on the intended route.

Answer 3

Do you think so? My intention was to keep the map as open as possible, leaving the actual routing to the player. There is not an intended route. That said, i was puzzled with that opening too: is kinda weird and somehow seems to break the "flow" of the level.

Answer 4

I went the entire loop and never actually saw where the ending was.  Thought you had used some black magic to make it so you could go either way but had to kill the enemies at the end of both paths, which i thought was a good idea.

Answer 5

I really really like this map.
