Dank, Sie das Spiel gespielt haben (How is our Deutsch? Our best German speaker hasn't spoken "auf Deutsch" in 5 years, and only had 2 years in high school training ;) )
That aside, you have our gratitude for playing the game! And you get applause for being our first streamer/youtuber recording a gameplay video of yourself. Unfortunately, we have no prizes other than pride in calling "First".
As for the lighting issue, that has been a general debate among our teams. See, the light plays a very important role within the game and allowing players to traverse the level in "pitch black" would break the game. However, from what we saw in the video - it seemed to also be an issue with our light switch layout as well as which lights each switch lit up. Your recording of someone (you) playing through the game with zero knowledge of the game and the gameplay has been very helpful and we will soon look for a fix in our next release.
Again - thank you for playing Eight Hours! We acknowledge it is a slower paced game that requires some patience when hunting down EVPs in each of the rooms in the house. Impressively, you are one of our most patient players seen to date.
As you progress there will definitely be entities to encounter - best of luck in your hunting of the paranormal!
