find bob

i made lots of minor changes but these are the major ones

1. i made a gravity flip script
2. inverted controls level 
3. flappy bird level
4. i made a story for the game (you can see it at the final level)
5. i made a final level that combines all levels into stages in it by making colliders that enable the stage state (such as flip gravity)

i designed a new character based on the player sprite
