Nitro+CHiRAL's VNs aside, I did play, and finished, Animamundi: Dark Alchemist, two of Langmaor's games (Enzai and Absolute Obedience), and Lkyt.

I did play No, Thank You!!! but I didn't get far (only up to Hiroyuki's route) and I've more or less forgotten what I did manage to play through...

As for what I've disliked, I can't say that there was anything that left a bad taste on my mouth. I guess at worst, I found Paradise's pace to be a real drag that I didn't feel like playing any further (I may pick it up again, but not very soon yet), and I wasn't even close to getting any of the endings yet. That's how slow it felt for me...
