Thanks for all your feedback so far! Please keep it coming.
Here's what's in today's update...
BUGFIX: Spiders now appear on the plank level only. They now disappear if you change floors.
UI: You can now change the rotation of the plank in Plank Setup -> Fine tune.
GRAPHICS: Started baking some shadows. Orange rooftop has them. Probably too dark for now.
PERFORMANCE: Added occlusion culling and adjusted realtime lighting for faster frame rate.
