While i really love the theme and the idea of a frozen lake with a secret cave, i find the building area quite small at the end (compared to moon sugar meadow and Coldharbour Surreal Estate).
Also, the lake is REALLY enclaved, you can't build anything on the rock or the snow since everything is blocked by invisible wall.
Here's a little drawing showing the actual wall i experienced (red) VS what i hope i would be (blue).
By comparison look at the size of the building area on moonsugar meadow!!!
Did you guys experienced any problem with these invisible wall?
