A mobile-first arcade game where you assemble a modular rocket from nose, body, engine, wings, and fuel parts under a currency budget, then launch it up a vertical obstacle course. Dodge meteors, storm clouds, and black holes while collecting gears, fuel canisters, and boosts to push for a new altitude record. Gears spent between runs unlock better parts, so each crash feeds the next launch. Built with Phaser 4 + Matter.js physics, with Wavedash-backed achievements and four leaderboards (altitude, max speed, gears, time-to-moon). Made by Piotr Chuchla and Miłosz Zajonc for Gamedev.js Jam 2026
