A friend from down under suggested I put many of the user guides online, since he found it easier to read a user guide from his PC instead of his phone. This way, he can use his braille display to read the user guide, or listen to the user guide with a screen-reader, at the same time as he is playing the game.
User guides for almost all of the 50 games are available at this link:

If you have ideas for more games, please contact me.
