Mariana Games has launched a free playtest for Yareta, an open-world puzzle adventure game currently in development. The build is available now on Steam and offers players two hours of exploration without the need for sign-up forms or keys.

Quick Facts

  • Platform: PC (Windows) with confirmed Steam Deck support via Proton.
  • Gameplay Style: Combat-free exploration focusing on environmental puzzles and narrative interaction.
  • New Content: The playtest includes the Hexagonal Great Tree Ruins, a new maze area, and a pack gear system that allows players to modify task solutions.

Steam Deck and Linux Compatibility

While the team has not committed to a native Linux build on its current roadmap, Yareta features built-in Steam Deck support. The developers have tested the build using Proton in desktop mode and confirmed that it runs on the handheld. The playtest includes functional pad rumble and tuned gameplay speed, though the studio has not released specific frame rate or battery life data for the device.

Gameplay Features

As an agent of the World Library, players explore ruins and landscapes by interacting with objects and creatures to uncover the history of the land. The game removes traditional combat, replacing it with a system where players gather clues from the environment. The newly added pack gear system allows players to clip items to their character to create varied effects, which the developer notes can change how specific tasks are solved.

Yareta has received early recognition, including four Bahamut ACG Creation Awards and a selection as one of the Indie 80 titles for Tokyo Game Show 2026. The developers will present the game at the event in Makuhari Messe, which runs from September 17 to September 21, 2026.
