HEAR ME OUT
do not judge this game by it's cover or lack of metacritic score. All the reviews I've managed to find are very positive, as is the reception on Steam.
I'm currently a few hours in and am very engrossed in the concept.
In terms of gameplay it plays like if Doom were a story driven game about philosophy and spirituality (some direct and many indirect references to the teachings of Eckhart Tolle) and also looked like Minecraft at times. It works.
Here's the eshop write-up:
Embark on a journey for answers to who you really are.
This Strange Realm Of Mine is a First Person Shooter mixed with Poetry and Psychological Horror.In REALM you explore your afterlife. On your quest you'll find characters in different situations, with their problems and thoughts on life. You can invite them to your tavern, a safe-haven in the midst of all the chaos. You'll also meet Ulrich, a spiritual guide who'll take you through your experience as a lost soul.
You'll come across monstrous beings who are eager to put their teeth in you. There are several ways to rid yourself of them, ranging from guns to melee weapons. Be ready to get your hands dirty and watch the blood drip slowly from the roof and walls.
Thanks OP, will give it a go based off your description.
