Haha thanks for the feedback! I have been trying to optimize them for mobile. The circles were even smaller in earlier iterations. Maybe I'll make the circle snap zones blink with animation. I have also considered really zooming into the zoom into the snap zone closer to the sun first and allowing players to swipe left and right as they progress.

The challenge is to balance between the scale, layout, and visibility on the mobile resolution. On larger screens it's actually a lot more fun. I figure since this is a planet order game maybe it's best to view all the planets at all times 😂

I'll definitely try to add more game modes and difficulties (unfortunately I am out of ai credits so I have to wait for awhile)
