Half and quater tiles
To place half/quater tiles, all you need to do is press CtrlF (⌃ controlF on Mac)!
Finer placement control
If you need to place objects with finer control, you can press F5 (you might need to hold 🌐︎ fn on Mac) on your keyboard to switch from a half-tile grid to a quater-tile grid.
To freely place objects without them snapping to the grid, press and hold Alt (⌥ Option on Mac) to move the objects around freely.
