You know that summary I gave above? Yeah, that’s pretty much the whole story.
There are six ‘heroines’, and each has one basic CG with a few variations, and that’s it. Notably for this sort of game, the game is voiced. That along with the competent artwork is all this game really has going for it. It’s not really worth the trouble, unless you just want a few more pictures of traps being raped for your collection.
