There's a button to run faster? xD
I reach my limit at copper medal, or maybe I use wrong routing, but I feel like I can only improve my score for 1 or 2 seconds, with more linear paths, better jumps on walls to avoid climb animation, but not that much.
The level design is nice to me, I got to rediscover some maps after wandering why a structure have been placed like this which makes it looks weird. So I'm like "there must be a reason" and try to reach it realising it connect to a shorter path.
