Oh, press B to enter? I tried dashing up, right and left on all doors but not pressing B....

Yeah its basically the stanley parable fused with an action game, here is my review on it =

Is this kinda like the Stanly Parable except more actiony and full of gaming references?

press Enter, or B on controller

stupid question: how can I enter the room?

Game looks dark. I hope there's a brightness setting.

its pretty fun game you won't regret it ^^ the achievements are pretty easy to get for the most part but some are confusing or missable

Ah. Had a holiday rush this past week at work, so I missed out on what the world was doing :P. Probably get this game soon...definitely hitting up your guide book (looks like a tough game).

i took alot screens mostly to use for my guide xD

Yup...I KNEW you were going to eventually get this game and post a million screenshots, same as I do with Skyrim :P.
