climb_work is a base speed (sniper / engineer / pyro) movement map that challenges you with tricky thin platforms and jumps of varying distances and angles.

give it a shot, the map is actually super fun. I found 3-4 little optimization tricks that will be interesting to see if others found too. the race i mentioned in the title is b4nny's challenge to whoever can run the map the fastest. winner gets the hat "Class Crown".
