The rpg elements are fairly simple, i think the gameplay shines in the character's roles as their respective classes, each with their exclusive skills that you can optimize to for whatever you want, the dungeoning is a good choice for party progression i think, THOUGH i find the weapons and armors to be the gameplay's biggest weakness, they're basically all the same with the progression being a bland tier system, it makes grinding for gear very boring.
The story is plain yet well executed and the characters are somewhat interesting and memorable (forever beloved my autistic awoo wife). The romance actually takes a part in gameplay (easy way to level up allies) so you actually have an incentive to partake and progress in it for reasons other than for the nsfw scenes, i think that's pretty clever design.
I play on windows 7 and never had any issues with bugs and whatnot, cool game, thanks.
