I just finished this game. Oh. My. God. Brilliant!!! It took allll the hints for me, lol, to figure out who the culprit was, but BY GOD was it was still satisfying! Ngl, that's likely because I'm just really shit at figuring mysteries out in general, so any level of success counts as a victory for me lolol.
I... Acc haven't played any of the Umineko episodes. Nor had I even heard of them, until now. I don't even really play mystery games. But I had it downloaded one day while browsing through some visual novels on here because the description probably made it seem like an amateur passion project, and I love to read those.
But this didn't feel even REMOTELY amateur. It may be just because I'm unfamiliar with mysteries, but the puzzles felt genius and the way you utilised the forum posts was bone-chilling. Not to mention how the realisation at the very end about everyone else on the forum hit me.
Absolutely no regrets, despite how unnerved it had me feeling by the end. Freaking loved this. I hope you have a damn good day, whoever's reading this.
