I downloaded it. It looks fun. Some of the jumps and lifts are a little tricky because the space is confined around them, but it looks nice for one of those "mess around" games. I think you should move the color balls to opposite ends, instead of having the whole map white. You could put red on the bottom and blue on top, or vice versa. I did that myself in Forge and it looked better, in my opinion, since the white is sometimes really over- powering.
Its only really a first attempt, theres a lot of things i plan to do to this map but at the moment i'm a little overwhelmed with ideas for other maps that i havent got round to finishing this one Thanks for the feedback.
I like arena style maps like this, worth a spot in my hard drive. This reminds me of Chiron TL34. Looks somewhat small though, I will give it a try though because pictures don't mean everything.
