First and foremost, the ui is extremely inconsistent, or unresponsive at times. Clicking many times on what seems to be the next option, only for you to start clicking elsewhere and for it to randomly work again. The phone ui is opaque at best, with some buttons having no function, either due to bugs or due to them not actually doing things. Some interactable objects just leave you wondering if they are actually supposed to do something, which they may or may not. It felt like I was playing a poorly designed point and click adventure game.
Artwork and erotic content is good, and there is definitely variety to the content to a decent level. As for unlocking that content you basicallygo through a checklist of actions for each character to unlock stuff for other characters. Not horrible thus far, but extremely tedious.
I tried to like it, but the opaque nature of what you are doing or why you are doing things, as well as it being so disjointed just made me give up after a bit.
Long story short, good artwork for the scenes themselves, horrible, opaque and disjointed gameplay.
