The arrow Key constants folded to the codes of w/s/a/d, which is what the
per-frame key reports for an arrow, but cocoa.ll has always stored an arrow in
the held-key set under 128-131. So Input.key_down(Key.Up) read the W bit and
Input.move_i's arrow half never moved anything. Input.key keeps its WASD alias,
so games comparing it with 'w' (snake, chronorift) still take the arrows.
New example input_arrows.ludic, checked by ludic-dev test.
