About Postmouse
Postmouse is a single-player, third-person puzzle-platforming game about a timid mouse delivering mail on their first adventure. Having always dreamed of the world beyond their little post office, Postmouse ventures into the unknown to deliver letters to people waiting to hear from loved ones.
The Yellow Woods
You explore a vast, ruined landscape set in an abandoned 19th-century mansion. The overgrown, handcrafted setting has a teslapunk style, with ruins from a time long past. Along the way, you meet and talk with the diverse residents of the Yellow Woods, hear their worries and may receive their help. The journey puts Postmouse in new situations and tests the boundaries of their comfort zone.
Puzzles and deliveries
You solve environmental puzzles, navigate treacherous climates and deliver the mail on time. You can also collect stamps for a local collector, earning concept art and background story.
