HOW TO PLAY
Your jet fires by itself. Just fly and dodge. Your hit-box is tiny: only the pilot's skull in the cockpit can be hit.
The chain skull guards your nose. Swing it with the right thumb: it eats little pink bullets, blocks bigger ones when it is moving, and bites enemies harder the faster it swings. It also shoots.
Weapon bubbles: shoot a bubble and it jumps to the next weapon (Rattlegun, Bone Spray, Zap Rib). Grab it when it shows the one you want. Same weapon again = level up (max 3). Pick a different one and your old one is stored: tap SWAP to switch.
Bombs drop by themselves onto the ground. Grey bunkers can only be hurt by bombs. The big BONE BOMB button wipes the bullets around you and hurts everything, and you are safe for a moment.
Hit and lose a level of your gun and a heart. Four hearts a life. Checkpoints give you lives and bombs back.
Gold crates burst into a fountain of pickups. Fly close to bullets (graze) for points.
