I have sent you another save game and in the mail also a way to reproduce it.
Thank you for this project. I enjoy it so much playing :)
Is it possible that in level 5 is missing some geometric data? For example when I go down the stairs at the bullfrog puzzle from level 4, the stairs are not on level 5 anymore and I can clip through. Also a bit further in from that stairs, there are parts without floor and I can just fall down out of the level
