------------------- ABOUT ----------------------
--
-- This map works as a menu for the hero hog to
-- navigate through planets. It portrays the hogs
-- planet and above the planets that he'll later
-- visit.

-- TODO
-- Save and Load All Check Points
-- Save hero health
-- Decide and implement if hero will use gas bombs...
-- ofc add custom stats page
-- PROBLEM : What if one makes a bad choice and wants to replay it map, how to reset?
-- POSSIBLE SOLUTIONS: In game function keys, frontend button...
