We’ve got something exciting to share, we’re preparing a private playtest of the Hollow Mire demo, and we’re inviting a small group of players to be among the very first to step inside.

This is a huge moment for us. After building this world, its characters, voices, atmosphere, and secrets, we’re ready to open the doors just a little … and see how it feels to walk through them together.

We’re calling it a closed, invite-only playtest, and it’ll include a carefully polished slice of the experience, featuring key scenes, exploration, and a few hidden surprises for those who look closely.
