The map, currently, is super well-made.
I love it, and its snowy aesthetic, but I think it could be BETTER.

Suggestions:

Breakable Windows
-Self-explanatory. The map would be more open for running/etc

Vents
-Could be anywhere, across the map, makes it more interesting.

Cabinets/Closets (big enough to fit players)
-Makes the map better for more contexts/etc
-Hide & Seek, etc

In summary, I'd like if the map had more hiding spots/secret areas, and were, in general, more accessible for hide and seek/survival minigames.
