DemoOnly the demo is playable right now.

You play an operator sent to alien planets to crack open crystals, haul them out and sell them, while the local creatures try to stop you. These creatures, the Telkar, guard the crystals. Some are small, fast worms and some are huge spider-like beasts, and they spit, slash and stomp at you the whole time you're mining. Each run mixes mining with fighting. You pick up upgrades during the run that change how you play, and the money you bank carries over into a big permanent upgrade tree. That tree is split into groups. Some make you faster or better with oxygen, some improve your laser, grenades and mines, and some add shields and armor. Others grow your backpack and speed up deposits, or add drills, drones, turrets and support like airstrikes and mortars. Runs start hard and get easier as the permanent upgrades stack up. It's a roguelite with incremental progression, so it fits players who want action with a long upgrade grind behind it. Steam lists the release for 25 November 2026, and there's an itch.io page too.
