It's not the worst locked room survival series I've seen, but none of the characters seem particularly interesting or likable, ten chapters in. The overt moralizing kind of puts me off too. No plot yet to speak of (but that's hardly an issue in the genre). Art is decidedly amateur (okay, it's not original One Punch Man, and still magnitudes better than me) but serviceable. Still, they read fairly quickly and the genre tends to be at least marginally entertaining for brief periods, so worth a look, despite the abysmal upwardly creeping rating. I'd give it a few more deathtraps to see if they're interesting enough to carry it forward.
