You're a revolver with wings trying to get to Paradise. You start with one bullet.
Hold right mouse to slow down and aim, shoot, then let go to reload. The recoil sends you flying and the gun tumbles around, so you have to get the damn barrel back on target for the next shot. Normal gives you room to screw up. In Hardcore, missing with your last bullet ends the run.
It starts at a shooting range. You'll go through the Frontier, Hell, Purgatory and Eden before you reach Paradise, shooting monsters and picking upgrades on the way. You shoot the cards to choose them, too. Bosses have weak points to break and drop chests you can blast open for more upgrades.
You can get ricochets, healing, a little gatling that follows you around, even a full cylinder if you're lucky. There are 41 stages, and if you still want more after Paradise, you can carry on in Endless. There's also a score leaderboard and a seed box to replay the same route.

I used generative AI and MCP tools for some of the art, 3D models, sound effects and upgrade icons.
