Nice spam. Yes, it's just these two circles. It looks real nice. I love how you made the map out of the infinity sign. I will give it a DL. It looks fun. I like figure eight maps, and this one looks very clean. Next try a banked figure eight
I'm sorry. I was just wondering if that was the only part to the track or if there was like an extension to a different area(that I couldn't see). I do like the over and under type of this track. I would suggest adding something like land-mines (not too many though) to spice up the gameplay and make the turns a little more challenging, or maybe in the top-middle section have a jump instead of a bridge!
I like the simple design. It shows that you don't have to have a lot of detail put into a map to make it good. The turns are clean, and it seems like the merging is clean as well. I don't really know the goods and bads of race maps, so all I can say is keep up the good work. There is one question I have, though: Do you start off in the middle of a turn, or at the small bridge jutting out of the middle?
This looks like it could be a really fun map. However I think you should make it suitable for battle tracks. I may even do it myself. The circles could create a lot of shooting. Which would add some excitement to the circles.
