If forced sex scenes wind you up, run from this game.
Technical
CG - Renders are quite good. The skin tones and level of detail are well above average. Also above average are the animations, especially the newer ones.
Audio - Background music is acceptable, although the mundane, elevator-style tracks start to become grating after a while. More variety, but especially more contemporary tracks would be nice.
Writing - Grammatical, spelling, etc are above average and mostly free of errors. Easy to understand (ie, English).
Artistry
This is where the game starts unraveling. The MC is mostly a typical HS level individual with limited intelligence and lack of foresight. When one reads the script the impression is the problem lies with the author. There are numerous logical flaws that just don't add up and one has to overlook what would should be, could be, more engaging dialog.
The biggest problem is lack of choice, which at first glance seems incongruent with the ability to choose a more altruistic vs corrupt path. But other than the interaction with the goddesses and their desires, the MC gets locked into relationships the player can't escape. And then the script turns the MC into a really mediocre liar that any reasonable female would have little tolerance for. But in his household and school, they (the women) have been gobsmacked by a -20 intelligence spell...or something similar.
Pros:
++++ CG and animations and attractive women (although personally I am not a fan of Rin and Lin)
Cons:
-- Story, script, premise
--- Forced Sex. Lots of it.
If you can deal with the forced sex, and just want to look at eye candy, d/l and play. If you want engagement and a compelling story, stay away.
