Thank you for playing! Glad you had fun with it! (and that you had fun with placing buildings around like that LMAO)
The building placement mechanics are definitely a little bugged at the moment (you can also build stuff in other areas you're not supposed to, like the grey cliffs and the rock itself if you move the camera enough), especially since it was slapped together after I spent a bit too much time trying to look through Unreal Engine tutorials haha
