AimDrag anywhere on the field. The barrel follows your finger, and the dial by your crew shows your range and the bright green band that does full damage.
PowerHold Space, or press and hold the field, and the bar fills. Let go to fire. Hold past full and the bar flashes and drops back to zero, then fills again, so release at the power you want. A quick tap lets go without firing.
FireRelease to shoot. Wind pushes the shell the whole way, and it only changes at the start of a turn.
DelayEvery second you spend aiming adds to your delay, and heavy shots add more. Whoever has the lowest delay fires next.
MoveHold the left and right arrows, or the buttons beside the MOVE meter, to walk along the ground before you fire. Every turn gives you a set distance and the meter shows what is left of it; when it is gone the meter says SPENT and comes back next turn. The barrel comes with you. Ground that is too steep stops you, and ground that has been blown away sends you over the edge.
ShotsS1 is quick and cheap. S2 hits harder and costs you more delay. SS only unlocks at a full gauge.
GroundCraters are real. Blow the dirt out from under a crew and they fall, and if there is nothing left below them they are gone.
KeysUp and down arrows aim, left and right arrows walk, comma and full stop trim the power, 1 2 3 pick a shot, and Space charges and fires.
