I can implement the player stats and other ideas in the next version which would be great! Thank you for your ideas again.
In GS1, controls were easier. There was automatic direction help and turning off the help was an option. In the new game as you mentioned D key (for dribble) and space key (for changing the foot you use hence the curvature) were the major additions. The controls are more difficult now but the variety of moves you can do became much more and more sophisticated so I decided to keep this manual style. Maybe in the next version I can add an easy mode as an option but I really want people to discover what they can do with the current version.
I always had South American football in my mind while making this game. I wanted it to be aesthetic and skillful. That's why the default teams are Brazil and Argentina :) All the best to you!
