Wow, seriously, thank you!
We appreciate your commentary while playing, and watching you play is invaluable. I am half the video and it is full of great insight, of which we are literally taking notes.
If you are curious, you can see in this video the optimal path to achieve 100% completion within 11 minutes.
It is only possible by doing a sequence break to get the Roll upgrade earlier. It is not a hidden wall or hidden path, it is clearly visible and it can be done by using the movement mechanics. It is shown around 3m33s.
Cheers
