Improved Platformer

This is an improved version of platformer game assignment, in which the player acts as a snail taking an adventure on the branch of a rose. Try your best to avoid obstacles and keep balance! 

Controls:

A or ←: move Left

D or →: move Right

SPACE:  JUMP

R: enter Rolling state when you are moving 

(hint: Rolling state destroys some obstacles, more effective when interacting with other creatures)
