Actually that worked for me yesterday. Thursday evening it was bugged (the popup would not load), but Friday morning it and evening it worked. Today I could not test, since I already own the game. Let's see what happens tomorrow.

Edit: Today it worked as well, so I guess that bug has been fixed for good.

Epic Games:

The Vanishing of Ethan Carter - Link

It is a mystery adventure horror game in first person perspective.
You follow Detective Paul Prospero on his investigation of Ethan Carter after receiving a mysterious letter.
Lovecraftian fans will love the psychological horror in this one!
Horror for the holidays

Here are some words from the developers themselves:
The Vanishing of Ethan Carter is a first-person story-driven mystery game that focuses entirely on exploration and discovery. It contains no combat or explosions of any kind.
If our game leaves any scars, we hope you won’t be able to see them. (haha)

You play the game as Paul Prospero, an occult-minded detective who receives a disturbing letter from Ethan Carter.
Realizing the boy is in grave danger, Paul arrives at Ethan’s home of Red Creek Valley, where things turn out to be even worse than he imagined. Ethan has vanished in the wake of a brutal murder, which Paul quickly discerns might not be the only local murder worth looking into.

Epic Games:

Loop Hero - Link

It is a card RPG game. I can already hear groans. Another card game? What's special about this one?
Without spoilers, let me tell you. Instead of playing as the hero, you... play as the environment
What?
You heard me. You control what happens around our protagonist.
Using a deck of magical cards, you place terrains and buildings and loot in the hero's pathways.
You can even place enemies and traps so be careful what you draw.
Upgrades are also available in expanding your deck and the camp.
Collect resources and unlock new characters and classes to join your adventure
It is your camp of guardians against the time loop of the menacing time looping Lich!

If you love cards and RPG, this game might be for you!
