1. Do not launch the game through itch.io launcher. The latest versions of the launcher break some games. Use manual launch from the game folder.
2. The newer the version, the more stable it is. In the latest version, I have never crashed the game for 10 hours of play.
3. Version 0.10 is the latest free version. New versions will not be free.
4. In older versions there were problems on android devices and weak PCs. In the latest version 0.38, the game is optimized as much as possible.
