Sequel?
These are just some of my suggestions if there is a sequel,
-Achievement Board
Maybe 500,000 points, 1,000,000 points,
-At least 1 more Surfboard unlock
Unlock 1 more Board, Unlocked all boards achievements
-Character Colors
My opinion, i'd like to see a choice of character colors.
Players should have to unlock them by maybe % game completion.
And Last, level of difficulty should be a choice, but again, the last few should be unlocked.
I really hope you put these ideas into a sequel.
