- Removed controls hint text and tile coordinate display from the screen
- Removed coordsText / controlsHintText fields and createCoordsDisplay / onCameraMoved methods
- Added keyboard shortcut reference block at the bottom of the ESC menu

 ## [Unreleased]
 
-### Fixed
-- **Y-based depth sorting** (Issue #31): trees, rocks, seedlings and buildings now use `tileY + 5` as depth instead of fixed values — objects lower on screen always render in front of objects above them, regardless of spawn order; build ghost moved to depth 1000
-- **Nisse always visible** (Issue #33): Nisse sprites fixed at depth 900, always rendered above world objects
-
 ### Added
 - **Försterkreislauf** (Issue #25):
   - **Setzlinge beim Fällen**: Jeder gefällte Baum gibt 1–2 `tree_seed` in den Stockpile
