This Track is very clever. I found for many of the jumps you wouldn't think you could make it but in the end you do, it's great, I managed to finish this track in good time( for me that is ) a few screenshots of me in action are available.
This is actually an improved version of a track I made for Trackmania Sunrise Demo. The track's theme is all about going up, higher and higher, till you get to the final long jump. Custom music, signs, intro, and ingame fx.
