This game is so simple and one dimensional that it is not much fan, but it is also somehow mind numbingly addicting in a way that doesn't let you put it away with ease. I ended up finishing all the levels, altrough it was more for the sake of challenge then actual fun.
My base score for the simplistic and boring yet addicting and challenging gameplay would be 3 stars.
From this I must substract one star for midgame ads.
And then I must substract one star for full version being available only in mobile. I just don't like mobile gaming. Why can't computer players play the full version? Especially since the game has ads anyway so it is already commercialized and developers earn money anyway? Minus one star for no full version for actual computers.
Final score - one star. Sorry.
