Damn, anisotropic filtering does a great job here. The shading looks nice, though I miss the old shadow casting. Terrain editing seems more limited now, but that's even better for landscaping purposes.
The standard left/right click feels underwhelming, instead of working like a brush it would be better to snap the shovel in place and allow user to adjust the terrain by dragging up/down. I have no idea what trimming does, to me it looks the same as leveling. I'm not sure how to use shift + control thing. You can make the selection stay indefinitely by releasing mouse and shift at the right order. Standard left/right click doesn't recalculate normals.
While unzipping on windows there's a conflict of test.png and Test.png file. I get a crash after fucking around too much:
/odin-urban-tycoons/src/quadtree.odin(312:28) Index 27 is out of range 0..<27
Other than that it looks and works perfectly fine. Still can't wait for wall editing.
