THE SPHERE COLLIDER

There are around you pellets of different colors. Reds make you smaller, faster and increase your score, blacks make you fatter and slower, and much rarer green which will significantly reduce your size and save you eventually.
There are three game modes. The Survival mode, in which you would play as long as you could, the Battle mode, in which there will be enemies who will chase you, and finally the Timer mode, in which you will have a countdown.
