Haha this is awesome. I can see how this can be addicting.
Of course I'd love to see the hand move its fingers as it walked across the platform, and possibly even able to move forward and backward. Would be cool to have an idle state of the hand tapping its finger to the music.
Im not sure if its applied already, but would be nice if it gradually got harder too!
Some powerups would be awesome! Maybe one could have the hand reach its pointer and middle finger straight ahead and would be able to defend against any eyes coming your way.
