A cardio game where your pulse drives the dungeon. Land inside the target and your hero crits, the combo climbs, the score runs. Fall off and the chain breaks. Real workouts, wrapped in pixel art instead of another bar chart.
No buttons. No tapping. The game reads your live pulse and turns effort into damage. Nudge the speed, incline, or resistance to hold the target; your legs do the rest.
Pick a trial and get moving. Your effort is the only input; there is nothing to tap.
One moving target, drawn from your own heart rate reserve. Inside it, hits land, combos climb, the score runs.
The target gives every minute stakes. Hold it and you are untouchable; let it slip and the horde closes in until you dig deep and push back. One dip gets a grace window, and even a cut short run banks its XP.
Treadmill, bike, rower, or elliptical. If it gets your heart rate up, it runs the dungeon. Bring your own machine; the game reads your effort, not your equipment.
Open the Watch app, leave it on your wrist, and your live pulse streams into the game in real time. Live heart rate is the whole game, which is why the Watch is required kit.
The Apple Watch app streams your pulse into the game in real time.
Built with the Karvonen method from your real resting and max heart rates, scaled to the intensity you pick.
Setup pulls your details from Apple Health, and finished sessions write back as workouts.
Each path is a real training style that builds a different part of your heart health. Every session levels all three, and your Heart Health Level blends them, weighted for balance.
Every path runs at 10, 15, 20, 30, or 45 minutes, across nine pixel biomes. Before every run you choose a Max Target, from Easy to Peak, and the whole workout rescales to it. The same trial is gentle on a tired Tuesday and savage on a good Saturday.
Nine pixel biomes, 22 enemies, three hero paths, and a fight that only moves when your heart does. Prop your phone on the console and go. No presenter, no leaderboard, no bar chart.
