Use WASD to move around this 3D field with towers, wieved from the top. To edit towers (and see some settings), hover your mouse to the bottom of the screen and click edit towers. Rendering types: 1. Building-by-building: Paints each building individually. May lead into buildings close to each other appearing wrongly on top of each other. 2. Layer-by-layer: Paints by painting the layers of all buildings together from bottom to top, so higher layers are always shown higher than lower ones. Looks better than building-by-building, but lags more.
