Boo is a tiny daily ghost game powered by your real-life data. Each day, Boo wakes up with a loadout generated from what you did up to yesterday. Your recent activity shapes today’s run through energy, shield, boost, and chaos. No wearable? Missing data? Boo still shows up with a minimum loadout, just a little underfed. At the end of each run, Boo gives you one simple physical recommendation, turning the game into a real-world action you can do immediately.
