Some parts are lengthy since its unedited. I looked up some of the harder puzzles since rigid puzzles are not something I like to spend alot of time with. This took around 3 hours to beat with figuring out some parts and looking up alot of the longer puzzles.
I also played through Chapters 1 and 3 but dont have those posted up. It was a while ago. I have some progress in another chapter but didnt like what I played of it. Chapter 1 was still my favorite. I believe there is one more chapter I didnt try yet, so I may play through it and post it up. One of them apparently had alot of block puzzles so I never tried it.
