A game of pool...

[kevin]

You made a cheat_mode in your game ... I like it  

Or even you could make it like an easter egg, too ... a secret key F5, so the computer would assist you to play your turn

That's a very good idea. In a similar way, I think it may have been good to include a demo mode in the menu screen, where you could watch a whole computer v computer frame being played out - this would give players a good idea how the game should be played. More ideas for future projects - thank you.
