Xalo — Orbital Command is a physics-based space game where you and other players launch satellites from a planet's surface and try to coax them into stable orbits. The trick is all in the launch: judge the angle and the speed, fight real Newtonian gravity (F = GM/r²), and aim for a diverse, crowded sky of satellites that actually stay up.

It's deceptively simple to play but runs genuine orbital mechanics underneath — orbit prediction with confidence scoring, six satellite types, daily/weekly/monthly leaderboards, and a few easter eggs (UFO encounters, comets) to reward poking around. Multiplayer is real-time over WebSockets, built on Excalibur.js with custom Canvas 2D rendering and fully procedural Web Audio sound — no audio files anywhere.

I mostly built it as a proof-of-concept for writing this style of game, and it turned out better than expected. It's on hold for now, pending fresh ideas and time.
