Dreadful Night (2023)

Blurb:
Wanna play a game? The only catch is, you’re not just playing it, you’ve got to play your way out of it. That’s exactly what is happening to Bada. And he’s been at this for a while, trying to gather clues and items to find a way out of this damn horror RPG. The killer, the NPCs, the setting, Bada’s now familiar with them all. He’ll just have to endure a couple more games, maybe get killed a few more times … But in this session, Nam Doha, someone who Bada thought was just an NPC, is suddenly acting strange. Has he been another player this entire time? Bada has to be tortured to end this storyline and start over and Doha has volunteered to do it, but the look in his eyes suggests he has other, even more sinister intentions in mind … What sadistic horrors must Bada endure to break free from this Dreadful Night?
