Too cramped intogether for my taste.
Try making bigger objects/ obstacles so you have time to play around before doing a new obstacle and needing to reething your workpace or whatever.
It's nice tough, nice idea, now make something even more interesting.
p.s love the climbing wall concept, but balls are a nightmare to get a hold of for a no grab parkourer, make tiny ledge blocks instead, makes it so much easier for both non and con grab users within parkour, even if it's the tiniest ledge it helps alot more htan a sphere thatäs almost impossible to get a hold of.
