I went to Portugal this year and tried surfing for the first time in my life
It was really fun and difficult. At the start, I was not even able to lie on the board
Even though I did not manage to surf any waves that day the mere impossibility motivated me to go on and on until we were forced to return the boards and suits
I would like to emulate the feeling in this game
Make it hard from the get-go, with no time for the user to get accustomed to the controls it must feel like learning how to surf
When you start getting a grip on the game you can unlock more and more stuff to do, not by changing the maps, but by getting better and better at controlling the surfer
There should still be some different places, maybe modeled by the real places where surfers go (from smaller to bigger waves)
