The control of my game should be holding left click to display circles that, depending on how far of the character it's the mouse position, it would appear just one circle or a row of circles one bigger than the other (to mark the strengh to which the player will speed burst) and when released, the char applies that force, bounce if there's a collision while being in middle of that impulse and then stops smoothly.
I.e: like Angry Birds, but instead of the player going backwards, white circles are displayed to show the strengh and the character isn't affected by gravity, it always goes in straight lines (when bouncing too).
