Drag with a mouse or finger to steer. Choose a fixed or floating joystick in SETTINGS. Fixed is the default on every device and stays where you press until you release. Keyboard: WASD or the arrow keys.

Face nearby foes and stand still to swing your sword. A wide arc hits a whole crowd. You keep facing away from foes behind you.

Walking gathers rain drops, up to three. Face a foe and stop to cast a straight bolt; each bolt spends one drop. You aim only at targets ahead.

Lift your finger and tap, tap with a second finger while moving, or press Space / Shift to dash the way you face. It costs stamina (the green bar) and nothing can touch you mid-dash.

Hearts are your life; slain foes sometimes drop one. A red ring or line under a foe shows where it is about to strike: step out or dash through.

Smash pots, open chests. Relics stack up to three per run: Swift Boots, Heart Amulet, Long Blade (Rain Prism for the frog) and Wind Charm.

The skull above the gate counts the foes left on the floor. Slay them all and the way opens; a floor arrow points to the last foes, then to the gate.

Five biomes repeat as you descend. New foes join from floor six: diving lantern moths, stomping golems and bombers with lit fuses. Every fifth floor a boss waits in the Crypt: the High Priest, and from floor ten the Warden. Pause any time with Esc or the button under your relics.
