A cave flyer in the spirit of Lunar Lander, Thrust and Gravity Force, built around one shared race a week. Thrust, rotate, and thread a cave that nobody had flown before Friday. No upgrades, no skill tree, no way to buy your way past a corner — everyone flies the same ship on the same track. The apps play offline too, even in flight mode: your runs are saved on the device and reach the leaderboard once you are back online.

Open beta. Play free in any browser at play.lunarghost.net, iPhone and iPad included, or download it for Windows or Linux. Your account, times and unlock follow you everywhere. Windows and Linux: unzip anywhere and run the game; it updates itself. Windows may warn about an unknown publisher the first time, because the build isn't code-signed yet. Android: in a closed test on Google Play for a few weeks first, as Google requires for new apps. iPhone and iPad: no app yet. That takes a Mac and Apple's yearly fee, and the €5 unlock is what pays for things like that. Until then, the browser version plays fine. Found a bug, or want a race? Join the Discord.

A ship threads a cave on the September 18 track, chasing its ghost and bouncing once off the rock

Six seconds of the September 18 track, chasing a ghost.

A ship with its faint ghost just ahead, over a rock ledge — Race your own ghost, or a friend's from a challenge link.

Sparks as a ship bounces off the cave wall — Clip the rock and you bounce. Hit it too hard and the run is over.

A ship landing on the green finish pad as the clock reads 15.15 — Land on the pad. A precise landing takes time off the clock.

Four ships in white, blue, pink and green lifting off the start pad side by side — Multiplayer: everyone in the room flies the same track at the same time.

Four ships spread out through a cave, mid-race — Online or on LAN, with a room code or a link.

Play every week for free. Pay to keep the old weeks, and to host online.
