NaissanceE isn't really just a game. It's an experience. And an amazing one at that. To start, as shown in the trailer, you are taken and thrown into a room. You have no idea where, you have no idea by what, and you have no idea why. Heck, you don't even know who you are. But thats not the point of this game. What you DO know, is that you need to LEAVE. As you progress, you get the feeling that something is wrong. Theres nothing out there hunting you specifically, no horror-game spooks. But you start feeling that something about this huge-scale world is... off. Like you just don't belong. The largeness of this world, the ambiance, how the entire UNIVERSE that you're in seems to play with you and mock you, is unsettling to say the least. As you spend time with this game you're no longer a person playing a game, you are the person inside NaissanceE. Every cliff you look over will make your heart race. When you are in complete darkness you will feel it.
There's no real storyline, per say. But after a few hours of play you almost understand the "storyline" anyways. The only real thing directing you on what to do is the checkpoints. Sometimes they read "going down" or something of the sort. But that's it. The ambiguity of this game is amazing.
Now for gameplay. Its first person, where you can walk, run, jump, and crouch. Theres certain mechanics you have to do throughout the game that require all of these functions. Some of the play is fast-paced, where you know you need to get somewhere RIGHT NOW and really feel a sense of urgency, while others is more laidback. The obstacles are fun, and the puzzles are puzzling. People have alot of problems about the checkpoints, but it's not that bad. There were some annoying times, but the way i see it, if im not annoyed at least once then the games not hard enough.
Overall, I highly recommend this game. Even without the gameplay, puzzle part (which is awesome), just the sheer number of times you just look at this world and think "wow.... I have to climb through all THAT?!" is worth it. The world itself is very playful, and this is undoubtedly one of the most beautifully made games ive played. Bravo.
