Catch comets with a tilt of the wrist and hurl them back at the sentinels that threw them.
Roll the phone left and right to move
Flick the top away to throw, or to punch a thorn back
Tilt the top toward you as a comet lands to catch it
Hold it tilted back to slow time
No tilt sensor here: ←→ move, ↑ throws (hold it longer to throw farther), ↓ catches, and holding ↓ slows time. On a touchscreen, drag sideways to move and swipe up or down.
Hold it how you'll play
Sitting, standing or lying down, hold the phone at the angle you'll play from and press Ready. That pose is level. The game follows slow drift on its own.

Turn the phone upright
Comet Keeper plays in portrait, so the flicks run along the phone's long side.
