About this game

REQUIRES: A Wear OS watch with a rotating bezel or a rotating crown. The game is played entirely with that input and will not work on touch-only watches.

A trunnion is the pin a cannon's barrel pivots on. Your watch's bezel is that pin: turn it and the barrel tilts.

You stand on top of a small planet. The targets are scattered around it — some ahead of you, some behind. Your shell does not travel straight: the planet pulls on it the whole way and the path bends. You lob the near one and swing the far one right around the planet.

Turn the bezel to set the angle, press and hold to charge. The charge reverses at the top, so if you have given it too much you can take it back before you let go. Six shells, four targets.

Every miss stays on screen. Those faint orbits are the game's teacher: you see where the last shot went and correct the next one against it.

SIX WORLDS, SIX GRAVITIES
On Ice it is 0.55 g and the shell floats. On Coal it is 1.60 g and the same shot slams down. The gravity is written across the middle of the planet, and you aim against that number. Each world has its own launcher, target and projectile: mortar, catapult, ballista, cannon; drone, balloon, orc, station.

Two visual registers: some worlds are spare and abstract, others illustrated.
Tap the screen to move between them.

• Six worlds, variable gravity
• Four launchers, four target types, five projectile types
• Past shots stay on screen as ghost orbits
• Works offline, no account, collects no data
• No ads, no in-app purchases
Turn the bezel, tilt the barrel, read the gravity and hit the target.
