what do the different crank options do (when you press B)?
Hi thanks for playing game :) so in general you can use special action with A and B just changes ability.
To use ability you need to decrease cooldown to zero.
1. Changes corner shells, any 3 match decreases the cooldown.
2. Changes vertical shells. Vertical 3 match decreases the cooldown.
3. Changes horizontal shells. Horizontal 3 match decreases the cooldown.
4. Swaps 2 marked squares (2x2) spaces. Cooldown decreases with any 4 match.
PS. Its cool idea to change the way crank works during game, shame I haven't came up with this.
PS2. Last gif shows sample of horizontal swap.
