Room of Time
A mere entertainment from Sharpknux; a novelty, quickly produced and with masses of his trademark textureless grey. We have seen something very similar in his work before, including a "hidden" section of Kami's Lookout - and I suspect this too is one of his DragonBall Z themed maps.
The big thing that this version has going for it is that it comes with low gravity, so you can leap around it quickly, instead of toiling through the grey trying to move from one of the pillared squares to another. That and a few nice weapons make it a fine, fun place to spend a few minutes in, but I doubt that it will ever find a place in any player's "top ten" arenas...
