This game is like a Gin and Tonic, it's an acquired taste. On the surface of things, It has a horrible amount of grind to it. You have to repeat scenes over and over to get to progress. The hinting system is vague and to progress you need to try each dialogue option to see everything. The animations are very basic (although getting better). The grammar is bad and the plot is ridiculous at times. If you don't have patience then this game isn't for you. If you can stick it out, there is some payoff (and it's getting better with every release).
Why keep playing it? All that grind gives you time to start imagining what might happen once you unlock the next scene. The hinting system tells you that there's a scene to unlock with a certain character, but it's up to you to figure out where. You jump around, day by day trying to find that next scene but it's never that easy. You have to keep going to school and keep your commune happy and make sure you sleep enough before you can even think about unlocking that next scene. When you do finally find the scene it's usually not that great but it opens the door to the possibility of an even kinkier scene, but you have to wait for the next update, maybe even four or five updates before you get the scene that you were waiting for. (At lease the updates are regular monthly releases.) While your waiting for the scene, something else happens. The same setup happens with other characters and you're eventually left thinking about all the twisted, kinky sexual adventures that might eventually come out of this game. Usually, the game doesn't deliver, but once it a while it does and that is what keeps you coming back for more.
In regards to the characters, for the most part they are very well done but some of the expressions are weird and overly exaggerated and the character's tongues are weird. Seriously, the character tongues are shaped like a snake's tongue or something.
