The graphics and sounds are very good, and the shader is also cool. The voice acting is very good.
But there are some problems, to be honest. I don't really understand what I need to do. There's a lack of a pause menu or something like that, because you have to use alt+f4 to exit. I recommend at least making it clear which buttons do what, because it's really confusing. It also feels like you're playing at 10 fps.
I hope you'll finish the game, which is why I said mostly cons than pros, because I think criticism is useful for developers, but the game is good anyway, especially for 7 days, so don't get upset about my review.
