Hushfen: Stealth Puzzle

A turn-based stealth puzzle: sneak an otter past herons, cranes, bitterns and owls, one step at a time, without ending a turn in a bird's view. 30 fens with par moves and pearls. Free download for Windows, Linux and Android; keyboard, mouse, controller or touch.

Hushfen is a turn-based stealth puzzle in the reedbeds. Each turn the otter moves one tile or waits, then every bird acts. Reach the burrow without ending a turn in a bird's view, bring the pearl home and do it in par moves for three stars.

• Readable birds: orange tiles show where every bird looks now, faint outlines where it will look after the turn
• Four kinds of watcher: herons stand and stare, cranes turn clockwise, bitterns patrol a path, owls look both ways and switch every turn
• Sneak tricks: hide in reeds, startle a bird by stepping on it from behind or the side, throw pebbles and step on creaky boards to lure birds away
• 30 fens in three chapters (Reedbeds, Lantern dyke, Owl wood); every fen was generated and solved by a search program, and par is the proven shortest solution
• Undo any number of moves; getting spotted steps you back one move
• Keyboard, mouse, controller or touch; English and Bulgarian
• Native builds for Windows (64-bit), Linux (64-bit) and Android (64-bit ARM); progress and settings are saved; no ads, no tracking, no internet needed.
