From c247dbc94a61b0860bccb1fa0d285a8f7a4deee8 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 21 May 2026 17:19:42 +0000 Subject: [PATCH] =?UTF-8?q?=F0=9F=8E=A8=20Palette:=20Improve=20score=20rea?= =?UTF-8?q?dability=20and=20CLI=20visual=20polish?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR enhances the "Speed Clicker" CLI game with several micro-UX improvements: - Implemented `formatWithCommas` to add thousands separators to all score displays for better readability. - Replaced manual space padding with the `CLR_EOL` (\033[K) ANSI sequence for cleaner, artifact-free terminal updates. - Improved the HUD with consistent bold styling for both labels and values. - Colorized the "NEW BEST!" message and added context (previous personal best) to the game-over screen. - Added `CLR_EOL` to countdown and "GO!" prompts to ensure a clean visual transition. Verified with `make` and `verify_ux.py`. Added unit tests for the formatting logic.

Furthermore, inclusive UX means ensuring first-time players also receive "New Best" feedback, even when their initial record is zero. **Action:** Update session-high-score variables immediately upon record-breaking and display them in the live HUD. Ensure achievement conditions (`score > highscore`) don't exclude the first-time user experience. + +## 2026-05-21 - Readability of Scalable Values in CLI +**Learning:** As numeric values in a game scale (e.g., scores), their readability decreases without thousands separators.
