One thumb. No mercy.

1. Drag anywhere to slide along the parapet — your thumb never covers the street.
2. On desktop, use a keyboard, mouse, or standard controller. Current bindings appear on the play screen and can be changed under Desktop Input in Options. With a mouse, the gargoyle follows the cursor — hold left to charge, right for bile, click the bird to zap.
3. Hold to charge. On touch screens, drag to move and hold SHOOT to fire — or switch on One-Thumb Aiming in Options: hold anywhere to charge, slide while holding to aim, release to fire. The faint ring shows where the shot will land.
4. Release to fire. Shots fly straight with travel time — lead moving targets, and watch the wind flag.
5. BILE (button or right-click): 3 per short run, refilled at each Endless Night stage, huge splash, triple points, turns victims into frogs. It also punches through umbrellas — nothing else does.
6. Consecutive hits build a combo up to ×5. A miss — or a blocked umbrella — resets it.
7. Hitting the constable starts a 5-second heat: the street empties and a lantern sweeps the parapet. Charging in its beam costs points.
8. The nun is −200 and kills your combo. Spare the nun.
9. A pigeon strafes the parapet and craps back. Tap the bird to call down lightning — Doyle's personal revenge. If it drops first, slide clear of the red ring or eat a −200 penalty and lose your combo.
