Well anyways, since I'm mentally ill I did the grinding anyway (with great help from save editor because holy fuck...).
I think it's undeniable that the artstyle is kinda rough, to say the least, but I still kinda like it. There's a certain charm to it, kinda like NITW. I don't think it translates that well into lewd scenes, but it's alright. I can easily say I'd rather 10 games like this than just a single one with those generic-looking 3D models. Look, I really like Illusion, but not to the point where every 3D has to look like that or worse. Regardless though, there's really little available, and they aren't that well executed. Animation is just a few frames toggling fast, and there's like 3 actually dedicated scenes, only 1 with actual sex.
With that said, I also think this game isn't worth the time. The grind is just insane, it almost feels like the dev will later try and sell me a battle pass or XP booster. And I say this as someone who likes slow-burners. I can appreciate that the actual gameplay is simple enough to be feasible on a crappy phone interface, but it's also a problem that it's this mind-numbingly easy and repetitive.
A single in game day earns you 15, each day you're deducted 5. Each gift costs 20, each gift raises affection by 3, and every interesting interaction requires from 80 to 90 affection. It's easily apparent how absurd this curve is. Especially with no gameplay other than "choose 1 of 4 options in a simple memory game".
