My very first platformer! You need to escape the void of the circles! The rectangles will always be there to help you. Red is bad and blue is bouncy. Yellow is your transport to the next level. Yes, you are a circle yourself but all the others has turned on you! Use the arrow keys to navigate the ball.
Thank you to @carzyhenryj for the engine! I WAS NEVER ABLE TO DO PLATFORMERS UNTIL I FOUND THAT! All levels are possible, even the one at the end. (Not the celebration one...the one before that.)
