Thank you very much for recording a video! The commentary was very usefull. You brought up many valid points.
That last bone you were having trouble with is very awkward to catch. There are many ways to get to the roof, but all of them will feel unintended. Also, I didn taught the mechanics in this build (my bad), but there is a "high jump" if you hold the Crouch button, and jump. That would help you a lot.
Thank you for playing! I saved your video for future reference.
