✨ Adult sandbox worlds by Kosmo Games

Hi! I’m an indie dev making story-rich adult sandboxes - modern-life drama Bright Past and new dark fantasy RPG Esterium Project.

🎤 Bright Past – life sim in a modern open world

2D sandbox about a young woman trying to make it from zero to the stage.

I’ve been developing this game for over 8 years as a solo dev, and it’s now fully released.

Explore the city, meet dozens of unique characters, write music, work different jobs (including more exotic ones) and choose how far you’re ready to go.

• Large open world with many districts and locations

• Dozens of hours of content and a lot of adult scenes

• Complete storyline, with ongoing post-release updates

▶️ Full version available now on Patreon and other platforms.

• Flexible character creation, choice of three genders and different playstyles

• Text-heavy storytelling and role-play choices

• Races from familiar to very exotic

• Your decisions shape who your character becomes

▶️ You can already try the early demo and follow the development, or support the project on Patreon and the same platforms above.
