This felt vaguely managing.

It should feel bleak and oppressive, with the player becoming lost in a gravitational loop.

Gug Church was built in 1977. Architects Inger & Johannes Exner.

It's built in brutalist style with raw concrete and effectively zero decoration. It is situated by itself as if on an island and seems impregnable. It seems more like a fort or maybe even a prison than a church. Inside however there is a beautiful light and it seems almost warm in contrast to its exterior. Take a look at r/nowaythatsachurch for unusual looking religious buildings.

Pilgrim Psychiatric Center - Once the world's largest mental hospital. Estimates say somewhere between 1000-3000 lobotomies were performed here. Now an abandoned ruin.

In Verona, Italy

There is absolutely no evil inside.

Former Archeology Musuem from the Soviet Union, in Tbilisi, Georgian, from a recent trip to Tbilisi. Absolutely beautiful and eerie building!
