This is an Alpha Demo version, so you might encounter bugs or misses. Also no features were removed except a time limit of 15 days. You can delete the user home Spacemen data folder: [userhome]/Spacemen folder and this will reset the time limit but also will delete any user content. You can also request a key on our forum which will permit you to extend the time limit without deleting anything. If you encounter any bugs or just want to send criticism you can find me at: florin-at-spacemen-dot-eu. Thanks for trying this out!
