This game does not need an installation. the Gamefiles have just to be in one folder. Maybe I will write an Installerpackage.
I don't know on wich Operating Systems it works, but I am sure that it will work on Windows XP 32 bit (Hopefully also on 64bit) and on Windows 7 32bit and 64bit.
You can run the configurator while playing and just change a setting, press "Save" and reload your game and the configuration will be set.
Nightmode is just a texturepack.
If you want to send the Game to others, feel free to do this. I will maybe post the Sourcecode, but for now I will keep it for myself. When the Game gets updated, there will be Achievements that will be saved on a profile you can generate and open with an extra programm.
Maybe I will add a new executable for starting the game to make it easier to handle.
