I didn't realize there was a white/black circle for a long time while playing. I kept looking back at the instructions confused why they didn't seem to fit the game. The black/white circle shouldn't disappear as soon as my finger moves on, otherwise I can't see it. I have no idea which spots are which color.

So do you understand the rules of the game now? Are you still having trouble playing? I actually think the game is already really well-made, and I haven't run into any issues playing it.
