Press \ to turn off/on Developer mode, it will cause lag The engine is not in its vertical slice yet, and is not ready for 3D games usage…yet You can climb the stairs, yes 0 - Low 18 - mid 30 - max (will be better, haha yes)
Everything has a auto-generated shadow and reflection thats interacts with light, and a hit box, the entire floor is a hit box, above 30 allows for DOF and Blur effects, the engine can run these settings on real time (30 fps) with 50 points, going above will be pain
