Page visits do not count as plays; the counter moves after you actually start the
game. When this version supports scoring, the leaderboard keeps your best submitted
result for the current build.

Tips
Check the controls before starting; browser games often hide the best shortcut in plain sight.
On mobile, use page fullscreen first so browser chrome does not steal touch space.
On desktop, keyboard focus matters: click the game once before using movement keys.
