My personal review up to EP 12:
I got to admit I may be spoiled by games like Being a Dik or Milfy City, but I think Sinful Delicacies is one whole level below those for different reasons. First one is gameplay. There is nothing to do as a player in any of the Episodes, besides clicking to advance the dialogues. No minigames, no choices to make, no puzzles, nothing. And this makes me feel like it's something external to me, that it's not "my story", like it happens when you watch a movie. This could be no problem in itself if it wasn't for the fact that the story is very hard to believe. Of course, suspenssion of disbelief varies from player to player, but in this case the MC makes no real sense: goes from randomly being a bad ass, to being shy and coy, to being cunning and manipulative, to not knowing how to do things, to doing highly complicated heists and stuff... with no real explanation of how he learned to do those things or why his personality is not consistent. The support cast works better, as the girls and other characters are fairly archetypical so they are somewhat believable as they more or less remain inside those archetypes (maybe with the exception of Candice, her whole plot makes no sense).
The other side that's on a lower level, besides gameplay and story, is the art. Renders are pretty nice, that's for sure, but not the highest quality around. And the game has no animations, which means that most of the action is either conveyed by alternating two images (jumping from one to the other to make it look like an animation) or by descriptions. And those descriptions are pretty repetitive, to be honest, but I don't hold it against the game as I understand the developers are not english-speaking natives, so it is to be expected.
All in all, Sinful Delicacies is decent entertainment, and has enough value in renders and so on to make it worth the play, but the deficits in all those aspects (together with other minor ones, like there not being a gallery to review scenes, or the repetition of tropes) make it fall in a decent level but nothing special. 6/10
