Game is good!
Good controls, grafics and audio. (And trippy carpets XD)
And some kind of story(Im sorry, but for me it feels like Postal 2 mission, go somwhere on other side map and buy goat milk and go back :D)
I have some strange visual bugs with light, in my case game looks like backdoors in silent hill :)
At begining all levels dark like that, but after reload lights become normal, as on your screenshots.
