OTTERCEL GO is an audio-first exploration game that gets people to put the phone in their pocket and go outside. The problem is mine. I love being outdoors, but a walk with no purpose is hard to start and easy to quit. I used to tell myself every walk was an "expedition" just to get out the door. So I built a companion that does that for me: a small, curious otter who gives you one mission at a time — "find something yellow near you", "listen for a sound made by water" — and reacts when you report back. How it works: you choose an environment (city, nature, coast or "surprise me"), tap Start, and the otter speaks its first mission out loud. You walk with the phone away. When you find something, you tell the otter what you found. Muse Spark reads your observation, reacts with a short, playful line and a fun fact, awards XP, and hands you the next mission. Skip anything. End whenever you like. No streaks, no guilt, no map — the world is the map. What I learned from field-testing it on my own trails in Lindås, Norway: I said I'd be out for five minutes. It was half an hour. That is the whole product. The otter's lines are generated live by Muse Spark; a small offline "pocket notebook" of missions keeps the game going if the network drops, so you are never left standing in the rain. The name comes from the spreadsheet I use at work, where every finished task turns a cell green. One green cell at a time — now one mission at a time. Built solo, in one week, by a non-developer with AI as my co-pilot.
