It is really nice to play it in Ren'py. I always feel dizzy when I have to find a specific location in RPGMAKER.
pro:
1, nice art, images are well-rendered, and modeling is amazing
2, straight forward to the content. players get corruptive easily and fast. (you don't have to grind at all in this game)
3, the number of images and the length of the game are shocking.
4, characters have been developed well. there are many roles in this game, and they have unique personalities and relationships with Anna. (dom/sub, S/M, blackmailing, sympathy, affection, and so on) Players can find all fetishes here.
con:
1, players can't go around cheating/NTR. Some other players might get upset.
2, stories don't stand out. Technically speaking, it is not a flaw, while the creator mainly focuses on lewd scenes. It would be perfect if the creator organizes the stories of Anna with different characters seamlessly.
3, I prefer more images in different poses than a looping animation with the same pose, personally.
4, there are many fetish/kinky contents in this game, but none of them get developed deeply. For example, the S/M only gets to spanking. and dom/sub relationships mainly stop at "rough sex" and collar/choker/chain.
If you are OK with cheating/NTR, and you come here for the fun of fetish/kink. This is the game for you if you want some excellent stories or pure love relationships. It is a big no-no.
