About this game
"I'm sorry Robert, I can't wait here forever. I have to find a way to leave this place" You are Caroline Miller. You find yourself on a narrowboat. The doors are locked. Your husband is missing. You're desperate to find him, but this place will not let you leave... Mayfly is a 'quiet' story-rich psychological horror where you must navigate your way through unstable and ever-shifting realities, finding clues and solving puzzles to piece together a deeply compelling mystery.

Optional side-quests and collectables: For players who wish to 'go deep' there are several optional puzzles and tasks to complete. Challenging puzzles: A series of varied puzzles to solve as you weave your way through an ever-changing environment. Emotional text: Emotive text-based 'story interactions' reveal Caroline's inne…
