Honestly, I feel kinda sad about fobs. I dont know if you've been following zell for a long time but I remember when he first made the earlier versions of Shiro no Yakata he proceeded to change the horror experience for a Succubus Affection kind of gameplay, eliminating the horror (I mean, the recent demos are not even scary, the earlier ones put you on stress and suspense at least)
What I really miss the most is Fobs. I love Sucubbus Affection and I know that he is making the sequel with the developer of the first one, but he even dropped the remaster he was doing of the original Forest of the blue skin. I loved the demos he launched, but it's been almost a year without fobs update, so I guess we are not getting it soon. Who knows, maybe he has been cooking the whole time and launches fobs remaster the next year. But with Tower of Shiratane, considering is a short story and we know almost nothing about the story mode, with the game being more of a gallery type, I'd give it another 6 months to actually getting to something good.
