It is one of the best simplistic, yet challenging puzzles if you don't open your eyes.
I've been playing a lot of puzzles lately and this one catched my eye cause of simplicity.
It literally put me back into the days when I was younger, those 2D games and everything, yet this is much greater!
Vivid colors, gantle music, I couldn't ask for better puzzle game to kill some time and to enjoy in it!
I would pay 5$ for this if that was the price, because you can get back 1/3 of your money with the steam trading cards that this game offers.
Pros
-You get awesome game for low bucks
-It's great even for a kid to learn few things
-It's great even for YOU!
-Steam Trading Cards
-Steam Achivements
Cons
-You can finish it in 1 hour

Over all, this game is perfect and I really enjoyed it, and will surely play it few more times! 10/10
