WiP Random Level Generator tied to a PCG tool

I have been tinkering with a level generator (path to room, and repeat, with extra side paths at the end) and wanted to see how well it could tie in with PCG.

It is all running in real time at the moment, mostly to show its steps, but it is surprisingly quick. Even the giant level generated at the end of this is fast: https://www.youtube.com/watch?v=p6-gjZ1kp9g

Anything else you think it needs, or any critiques?
