/* 
TODO:
--------------------
Bugs:
* Consider shaft method for difficulty ramping.
* Now that player graphic is bigger, it sometimes collides with platforms from below. Either adjust size, spacing
or jump height/logic.
* Maybe player should have three lives - shown as little red hearts in top right corner.
---------------------
Interface/graphics:
* Show instructions on screen at start.
* Maybe elephant should face the last direction it moved.
--------------
Powerup ideas:
* A powerup that removes all nearby platforms and give score for them.
* Maybe make a disco powerup that changes light, colors or visuals somehow.
* Consider platforms that increase or decrease the size/weight of the character.
* Or maybe just a platform with a piece of cake on it, and when player lands there he gets 10 points and swells up
(no gameplay side effects) for 5 seconds. Could actually be all kinds of funny pickups like that.
* Different hats that the player will wear until a new one is picked up?
----------
Gameplay:
* Consider difficulty ramping. More red platforms?
* Make sure red platforms never fully block the way. Platforms have row and column id's to pattern match against.
-----------
Theming:
* Consider possible player character.
* A frog? A kangaroo? A spring? A tennisball? A rabbit? A two-headed squirrel? Something on a pogostick?
* A Rick Dangerous finding treasures on the platforms?
* A Pirate Ship finding bounty on platforms? Maybe beats platforms with less strength than they have?
* A cat eating sushi on each platform?
* A princess saving animals on every tenth platform?
* Maybe all those characters, each triggered by a powerup until a new one is picked up.
* Maybe new mode unlocked per 200 platforms or so?
----------
