Greetings,
I have read through your draft. It has inspired me to work on Shivergate(a Thalasso threshold)
Verglas is a cool name! I am going to borrow it >:)
Anyways, I have some feedback for you.
FEEDBACK
I like the idea of an endless freezer room maze. One of my fears is being locked in one of those and freezing to death.
However, it is not really liminal. The Verglashoes are pretty interesting but the Butchers are bland. A lot of ideas are started but not expanded upon. It is really simple.
Chamber 9 is slightly interesting but doesn't make sense. How could they survive that long with the low temperatures and all the entities?
The best part that I read was the existence of "Infinity Aisles". From the sounds of it, it is a supermarket or something with a freezer section. That is a pretty cool connection to another level.
In the end, this is an OK first level. You should probably join the Discord(if you haven't already) to get some more crit.
