Very simple and addictive game. You will surely not beat this one on your first try, as the levels get more and more challenging as you advance. Soundtrack is fairly good, is up to the game's mood, though it gets a little repetitive after a while. I felt some levels were easier than their subsequent but just like in many other games i've played. A second part would be very welcome with some minor adjustments in the soundtrack and maybe more some more levels or a level editor could be a great addition, but it's up to the game's creator to study (or not) those possibilities and see what (s)he sees fit.
