It's a good game. Due to the animation tag, I was expecting... you know, "animation". The best you see in this game is a slide show of 3 images slowly changing, from no pen, mid pen, and full pen during sex. 1 "animated" scene per girl (and there are quite a few non-animated scenes as well, with multiple images). I hate to rag on this because the game is good, it just didn't meet my expectation here and this would cause me to drop a star.
However, it did exceed my expectation in audio, specifically there is really good voice acting in this game. Seriously, the dialog is kinky AF and the voice actress(es?) read the lines like champs. All dialog from the 4 girl characters is voiced and voiced well. I haven't seen that in an H game before. Dialog in H games are so much kinkier than dialog in porn, right? Like you don't often hear a "breed me son, be my master and impregnate your sisters too!" in porn lmao, but it was voice acted and put in this game (not exactly, but you get the point). For this reason, I am giving the game the star back.
It was a unique experience due to the voice acting. The art and characters and story around the acting is ranging from "okay" to "amazing", but the voiced lines just really made this game something you don't see every day. Not a game I'd usually give 5 stars to, but I have to give credit where credit is due.
MUST READ: To get the harem ending, you have to watch all of the individual endings til the credits first (and, obviously make the correct choices so that you have the 4 endings available to chose from). So, save your game BEFORE the screen with the dialog choices (where the game tells you "Last Chance"), watch the 4 endings, and then you can watch the harem ending (it's good).
