Very fun and creative. I wish it was just slightly easier, I feel like half the fun is taking risks and attempting higher jumps when the time is getting short, but each piece of the tower seems like it has the "correct" way to scale it and I keep messing up if not going exactly by the book. I feel like grabbing onto ledges is a bit too punishing at the moment, maybe slightly increasing the effective area for grabbing?
Congratz for a great submission!
