While the game itself, like it's predecessor Pixel Puzzles Japan, is quite enjoyable, it still has the same key issue: you cannot save the puzzles, a thing you can do with real life puzzles even. It is also somewhat easier than the Japan version due to using drawings instead of photographs.
There's a tacked on "survival mode" with a shooting game going on in the lower part of the screen, as a kind of hard mode. A nice idea, but mediocre in execution.
Images vary from good with funny motifs to half amateurish, which is a shame. There's fifteen puzzles in total, if they had gone with their better illustrator for all of them it would have uplifted the whole game.
What finally prompted me to go for a negative rating (instead of saying it's mediocre and still giving it a thumbs up) has to be that one last achievement though. Completionists, stay away from this unless you are prepared to suffer!
There's a menu mini game, which has several achievements tied to it. Some of them are for killing a certain amount of menu zombies. The first ones stack, the last one apparently doesn't. So essentially I'd have to start all over again for that last one, because I was tricked into believing I could give my eyes a rest after over an hour of the most boring(!) achievement hunt period.
Doing hard achievements is one thing (and welcome), but this was simply a sadistic and dirty move from the devs on behalf of hunters. So, to return that "favor": here you go, Decaying Logic, while being overall not very much disappointed by the game, I choose to make that one, tiny last bit under my review a big thumbs down. Feels good, feels right, doesn't it?
