Flick Club/Controls
Flick Club has 3 different styles of control you can choose from. You can either use a preset or bind the buttons yourself with one of the custom settings.
Dual
This is the default control scheme. With this you can move your cursor in 4 directions, and can flick tiles in 4 directions. It is similar to the dual control style from Petal Crash or Crossniq+
Y2K
This is a control scheme similar to the default controls of Crossniq+. you can move the cursor in 4 directions, and by holding down a button you can then flick a tile in 4 directions, moving your cursor along with the tile
1992
This is a control scheme similar to Yoshi's Cookie. You can move the cursor in 4 directions, and by holding down a button you can then flick a row or column in one of four directions, keeping your cursor where it is.
Playing on stick or hitbox
While stick and hitbox can use Y2K and 1992 pretty easily, Dual is a bit less intuitive. A common remapping is to put the flick buttons for left, down, and right on the top row, and the flick up button on leftmost bottom button. Sort of like a mirrored hitbox directional layout.
