Really good game!
First of all the characters are well made and the game generally looks really good, the scenes are well made and are original for every character so progressing and repeating everything for the sandbox/training aspect is always enjoyable, especially with all the diferent themes you can interact with so all in all for a hentai game it's really good.
Now for what i didn't expect going forward was just how in depth the worldbuilding actually is and the story and progression are actually well writen imo (or at least i do enjoy it) so much so that i ended up caring more for the story than my initial reason to actually play the game xD.
It truly shows the more you progress the story with everyone and I really hope that everything can be tied together at some point cause enven though there are sometimes bits and pieces mentionned from another girls story (info you may have learned) it remains anecdotal and the MC himself makes educated guesses like "oh it could be that, but that's not the focus rn" and so each story still feels a bit detached from eatch other... Now admittedly i just haven't finished lins story but i did finish with every other character.
TL;DR: I really do recomend playing this game and supporting the dev if you can because it's really well worth it and there really is a lot of good content and there's more to come.
P.S: I've also seen some people saying the game is abandonned but i don't think so? I mean the last dev update at the time of writing this was 2 montsh ago so there's still communication going on so it doesn't seem abandoned to me y'all need to chill, real life can be a pain and i think we all can understand that '-'
