# Patch notes

## 15.20.3

- Removed item-effect speech bubbles: `ドン`, `ぐるる`, `すっきり`, `Hg xN`, `ちまっ`, `でかっ`, `へにゃ`, `ムキッ`, and `mm...`.
- Reorganized the tool palette into color-coded collapsible groups: operation, food/water/grass, medicine/effects, habitat/living things, hazards/obstacles.
- Changed the tool UI ball icon to a soccer-ball emoji preview.
- Changed time phases: morning 05:00, day 10:00, evening 17:00, night 20:00.
- Increased genkotsu knockback for Tarinai and ants; genkotsu now also blasts zunchi away.
- Genkotsu damage now adds fear/stress and decreases Tarinai openness.
- Rain weather overlay is now diagonal streaks. Fallen rain-water items, zunda juice, and mercury remain horizontal oval item sprites.
- Tightened mobile operation UI visibility to smartphone-class compact touch devices.
- Sleep-disease Tarinai can be moved by ant hauling without snapping back to their sleep anchor.
