One of the two PS4 launch "free-for-PS+-members" games is Contrast. The best way I can describe this game is that you play as a little girl's imaginary friend (a shadow), and it's your job to help her through a variety of levels by shifting in and out of shadows and solving puzzles. That's the best way I can describe it without spoiling the story for you.
Graphics: Being a downloadable game, and one that's available on PC and 360 already, Contrast isn't exactly a mind blowingly attractive title. The art style is interesting and easy to appreciate, and the level design is pretty nifty. The sometimes awkward camera angles, occasional glitches, and framerate hiccups keep this game from getting a high rating from me. Still, Contrast has a definite charm to it. 3.5/5
Sound: There's not much, but what's there is decent. I enjoy the music in the game (though there isn't much of it), and the voice acting is fair (even GOOD at times), but it's pretty average as a whole. The music definitely helps give you an idea of the era though. 3.75/5
Control: You use about four buttons throughout the whole game. You move, jump, hit, and move in/out of shadows... that's essentially it. As simple as the controls are, the camera makes the game a bit frustrating at times. Not throw your controller at the wall sort of frustrating, but annoying nonetheless. 3.25/5
Fun: Contrast is a game that any PS+ member should download, considering it's free for a limited time. While the game isn't particularly long, and the story is all over the place, it's fun for the time you'll spend on it. Contrast isn't a very difficult game, but you'll have to think for some of the puzzles. It's nice that Contrast isn't a very long game, because had it gone on much longer, I'd've felt like it was getting repetitive. I'm not too sure I could recommend Contrast at its normal price ($15, I believe), but it's entertaining and lengthy enough (three hours or so) that even if you do get it at that price, you'll have a good time. And hey, the trophies are very easy to get, if you're into collecting them. 3.5/5
