Are you ready for the addictive arcade game that requires only one touch? In Ooval, you are a happy ghost. All you need to do is switch between the inside and outside of the circles to collect the purple points. Sounds pretty easy, right? Mind you, you're sure to encounter some tricky obstacles along the way! First, don't hit anything while moving through the circle. You can only change circles while you're travelling around the inside. If you touch another circle while you are traversing the outside, you're done for. Do you think you have the skill to make it?
