Stupidly big rooms, with high r_speeds, bad item placement and really poor game flow. Its a long way between rooms and even from one side of a room to the other and the teleporters aren't really doing much to help the connectivity. There are a number of secrets, probably too many. The BFG trap could have been left out all together. There are some nice features, the author will probably do a lot better on the next map with the experience gained from this one. Bots play ok until they get close to a secret.
Lots of work, just plays poorly.
