Some of the artwork...the slime, cum, and other various liquids, the clothing, and the environment during sex scenes... are astonishingly well done. Some artwork...the walking-around environment and the main characters face and hair...are adequate but nothing special. The rendering of the clothing and how it is lit under different circumstances really stood out in comparison to the rather bland rendering of the face.
Outside of the look of the game, I can't say I had a lot of fun. It was fun to look at during the sex scenes but the rest I found to be confusing and maze-like. However, it was one hell of a work of art to be lost in.
If how a game looks is more important to you than how it plays, give this a try. The stunning graphics may appeal to you so much that you don't mind wandering around lost.
