Just finished Deadlight
. Man, what a game! Okay, it's only 4 hours long (at least in the normal mode, haven't tried the nightmare mode nor the ranked game), but that's just perfect for that game!
I'm not usually big on zombies games, but that one caught me right from the beginning. A side-view platformer/shooter/enigmas games with lots of tricks and exactly the right amount of difficulty to be not easy while not beaing frustrating. There's always a way to continue to progress in the game, you have to use your wits, and that's nice.
And the scenario, well, I can't say a thing about th scenario, since it would ruin everything, but believe me, Deadlight is a well-written game! I'm happy to have found this nice little gem!
