Also this month I plan to continue the level greybox.
I am building the second part of the level, where it will rejoin the starting point via a shortcut. I think I've gotten better at greyboxing. I'm hurrying a little bit and probably I am a little less consistent with the placement of props (barrels, crates etc.) so some rooms may seem a little more empty.
When I finish the greybox I'll have to place enemies and to set some traps, it will be a lot of fun and I'm looking forward to it, but for now I have to focus on finishing the level.
