Open Source Kotlin Side-Scrolling Games

Astro Loop is an open-source roguelike space shooter for Android that combines accessible controls with increasingly challenging survival gameplay. Players pilot a spacecraft through endless waves of asteroids and hostile enemies. Movement uses simple one-finger steering, while weapons fire automatically to keep the focus on positioning and survival. Each run offers different weapons and upgrades, encouraging experimentation with combat strategies. Players can recruit additional pilots and unlock new spacecraft to expand their available options. Difficulty progressively increases as players attempt to survive longer and overcome increasingly dangerous encounters. Developed entirely in Kotlin using Android Canvas, Astro Loop operates offline without advertisements, tracking, internet access, or sensitive device permissions.
