I added WASD support and updated the UI so players can use W/A/S/D as an alternative to the arrow keys. To make the change clear and intuitive, the in-game control hint and the instructions dialog now mention WASD, and each on-screen arrow button displays the matching WASD letter so both control schemes are visible. This improves usability for desktop players who prefer WASD and reduces confusion about available inputs. I verified the change by starting the game and doing a short playthrough: movement works with arrows and WASD (uppercase or lowercase), swipe and on-screen buttons still work, scoring and level-up behavior remain unchanged, and collisions behave the same. The changes are intentionally minimal and non-disruptive. Next steps I can take: add simple styling for the WASD labels to match the UI, run cross-browser checks, or add a small accessibility note about keyboard controls—which would you prefer?
