The closed Sublustrum playtest is live!
The playtest will run until September 14. During the test, you’ll have access to a demo version of Sublustrum featuring the first part of the game — explore the environment, search for clues, solve puzzles, and begin unraveling the mystery that sets the story in motion.
Please note: access to the playtest is available to a limited number of participants. If you previously requested access on Steam, make sure to check whether Sublustrum Playtest is already available for you to install.
What we want to learn
For us, this playtest is a chance to see the first gameplay experience through your eyes. We’re especially interested in:
how comfortable exploration and interaction with the environment feel;
how clear and well-balanced the puzzles are;
how the story, pacing, and sense of mystery come across;
how the visuals, music, and atmosphere work together;
how stable the game is and whether you encounter any technical issues.
And, of course, we want to know the most important thing: how the experience made you feel, and whether it left you wanting to discover what happens next.
After finishing the playtest, you’ll need to complete a short feedback form. Playtest participants will find the link directly in the game.
