After internal testing and closed playtests, open playtests will begin shortly, and you can now sign up for them.
The goal of the playtests is to gather feedback about the game and identify potential bugs and issues. The tests will only be open for a few days, and the collected data will be used to create a better demo.
Due to the short timeframe before the demo release, language selection in the game is unfortunately not yet available (only English is supported). Similarly, a native Linux version is not available yet. These features will be added in future demo updates.
