Dreadful night

Dead man switch

Not a manhwa, but I just recommended a danmei with the same vibe as Dreadful Night to someone else: If u are open to reading danmei, the first instance in Mist takes place in a cycle where you have to die to reset time and make progress. Since it's the first instance you only need to read the 3 introductory chapters before getting into that part. It's done really well and similarly to Dreadful Night, there is a lot of technical aspects to the way things "loop." KK Translates posted their translation so you can find it on their site.

Thank uヾ(☆▽☆)

Hi! Looked up “mist” on kk translates and i found chapters 1-3. Any idea where i can find the rest? (￣∇￣")

The rest are available but just password locked. There should be a section on the top that says passwords or something similar where it tells you how to unlock the rest of the chapters. Let me know if u can’t find it

Found it, thank u smヾ(❀╹◡╹)ﾉ~

its not puzzle solving but the mindbreak will confuse you like damn: Moritat
