Pithead Studio, founded by ex-developers of Gothic, recently presented a demo version of the Cralon project on Steam.
The protagonist in Cralon is Cralon the Brave, who is tracking down a demon who is kidnapping residents of a neighboring village. As a result, the hero falls into the shaft of an old mine and now he has to explore a labyrinth of corridors where dangers await.
The Cralon page on Steam is available at the following link. Depending on the speed of passage and style of play, the demo can be completed in 20-40 minutes.
