"WASD" or "ARROW KEYS" to move ninja. Sword: "1" to equip, Left click to swing the sword. Ninja Stars: "2" to equip, Left click to throw the Ninja stars why facing the direction you want it to go. Grapple Hook: "3" to equip, Left click to throw the rope with your mouse in the direction you want it to go. Left click again why the rope is being thrown to cancel the rope. Equip a different tool, why throwing the rope to cancel it. Nothing: "0" to equip nothing
When you equip the grappling hook and unequip it there is a back dot, on the screen, I don't know how to fix it though. The ninja stars use some hacked blocks, that is "Counter", "Increment Counter", and "Clear Counter" because it would have been way harder without them.
