Interstellar Cat Girl Expansion: Idle 😻🌌

Interstellar Cat Girl Expansion: Idle is Ubera Games' early-access simulation where you captain a space mining vessel staffed by cat-girls with transformative, body-expansion focused adult content. You begin broke and alone, gradually earning credits to recruit crew members, upgrade your ship, and explore distant planets. The core loop revolves around mining asteroids, refining resources, and sending expeditions to gather rare artifacts that temporarily boost your crew's abilities.

Gameplay centers on idle mechanics—resources accumulate passively while you manage crew recruitment, skill upgrades, and expedition planning. The v0.7.0 update introduced planetary exploration, where you dispatch crew members on missions to find artifacts and uncover new worlds like Proximu. The game includes scanner systems to sort asteroids by rarity or distance, navigation upgrades to accelerate expeditions, and a tiered refinement system that prevents over-processing resources. Adult content focuses on transformation and body-expansion themes woven into crew interactions and character development, handled with mature framing rather than explicit depiction.

Be aware this is early alpha (currently v0.7.0 publicly; v0.8.0 beta available to SubscribeStar supporters). The game does not run on Firefox—use Chrome, Edge, Brave, or another Chromium browser. Performance has improved significantly since the mobile update (v0.6.0), and a Linux/Windows build exists for backers. Expect ongoing balance changes, UI refinements, and new crew members as development continues. The game is playable in HTML5 and on Android.
