Create your own take How to play Moonlit Courier
Collect at least eight letters and reach the mailbox across three connected scenes. You start with three hearts. A missed jump returns you to a safe roof while hearts remain.
- Desktop controls
- Click Play, then press Space, Up or W to jump. Hold for a higher leap and release for a short hop. The cat runs automatically. Escape, P or Pause freezes the route.
- Phone & tablet controls
- Tap the scene or hold the Jump button with your thumb. Hold longer to clear a gap. The portrait camera shows the roofs ahead; rotate your phone for a wider view.
A useful starting tipWatch the lamps that mark the edges ahead. Hold your jump across a gap, and use the striped awnings to bounce higher. Spare letters let you miss some pickups and still finish the delivery.
Use full-screen play for more room on a phone. Restart starts a fresh run. This game is free to play and does not need an account.
