Dot... dot... DOTA! It's a game of skill and of course of dots. U are tasked with a very, very important task. One that will tax ur timing abilities to the max. U must make ur dot move from the heavens above down to the earth below and back again... as many times as u dare.
Of course, as with life, things are never so easy. Watch out for floating sentinel dots that will want to stop u. Do not to hit them unless u love seeing game over dude... GAME OVER!
Just be patient and tap when u need to tap. How many times will u do it before u fail? Failing is part of life... just try to succeed more than u fail, right?
