Game finished and uploaded! :-DYuuuuuuujuuuuuuuuuu! finally I have the game more or less as I had planned it.
I hope you enjoy at least a little and, of course, suggestions or comments will be welcome :-)
Playing the game shouldn't be as complicate as my last entry in pyweek 10.
I'm looking forward to seeing the rest of games to play.
And now I think I deserve a very big cold beer :-D
