Petalrack - Controls

Touch and mouse

Tap a cluster in the tray to hold it. Tap a soil cell to set the held cluster with its top-left on that cell. On the title screen, or after the bed fills, tap anywhere to start a new rack.

Keyboard

Arrow keys, or W A S D, move the ghost. Enter or Space sets the held cluster, and also starts a rack from the title screen. Keys 1, 2, and 3 pick a tray slot. Q and E step to the previous or next cluster that is still in the tray.

Fullscreen

The Fullscreen button on the game page expands the rack. Your best score stays in this browser either way.
