This is quite possibly the best written game on here. I do not say that lightly.
The premise is a touch cliche, but thats the point. The game is a subversion of the 'hero harem' genre that you see so much in japanese media these days.
The writing quality blows 99.9% of games here out of the water.
Characters are well fleshed out, realistic and all with their own motivations, characteristics, mannerisms, quirks and most importantly - flaws.
The author does a great job of portraying both male and female psychology, especially with cecille and elena and mars and erin.... and yvette.
The story is somewhat of a slowburn, but it has fantastic pacing. The corruption is slow, insidious and VERY well written.
The plot is very unique, and i honestly was surprised by some of the directions it went. (Its pretty rare for me to be surprised by a story these days)
The game isnt afraid to take quiet moments with each character, aside from the main plot. This lets us players have intimate moments with each love interest, and it really makes each character stand out.
The scenes start fairly tame, but were always drawn with a decadent feeling to them. The scenes get progressively more depraved the longer you play. I found some of the middle/later scenes to actually be very fappable.
There are a LOT of fetishes in this game. It just so happens that all of them do it for me, but if some arent to your liking, the game doesnt force any of the especially wierd ones on you... too much.
The artwork is really impressive. It isnt on level 'my pig princess' but it IS unique, and has only gotten better and better since the dev started creating this gem. Characters faces are very expressive, and his surreal anime style is really hot to me. The art has a dirty, gritty, wet, sticky feel to it - what i mean by that is that for many sex scenes in games the scene takes place in a clean room with mostly clean characters. THESE scenes look humid, and the characters end up looking sweaty and dirty and overheated - like theyve ACTUALLY had good sex.
The music is actully amazing. The sad scenes have sad music, the happpy scenes have joyful music, the dark scenes have eerie music - just like a proper game you might buy on steam. The sex scenes actually have hot music. There is one in particular that i actually downloaded into my sex playlist for personal use - its that good.
Lastly, the dev works his/her ass off to get regular updates out, and doesnt cheese patreon. The dev is pretty active on discord and gives feedback and updates on progress regularly.
