Support keyboard-only play

The problem

Mouse-first interfaces exclude players who cannot use precise pointing.

Practical procedure

Map arrow keys and WASD to the same movement function used by touch controls, and prevent arrow-key scrolling during play.

Worked scenario

A user should finish the first puzzle without touching a pointer device.

Acceptance check

Tab through all controls and complete a level using only keyboard actions.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
