I advocate, that this game gets a sign reading "Welcome to the Insects x Fighting Nun Hentai Scene Gallery" with some with some stats, attack names and some good ol' damage numbers as a decoration.
The story is pretty simple as you get to control an advocate of Good to search and destroy some Evil. Do not expect any emotional ride except coming down from your horniness after the nut.
There are allusions to a plot having happened at the place you are exploring, but what can I say about it other than that dead men tell no tales.
The game is practically linear with a bad end here and there. Most of the time you are trying to find a cube to put into a quadratic hole like a toddler, except you are most likely an adult and could flex to a toddler with your speed in that game. Sometimes you get into a fight, which ends up with a game over due to being underlevelled or you winning and carrying on. Skill Usage and therefore some kind of strategy is rarely needed. The bland fights only get a bit of spice due to the erotic attack cut-ins of the enemy attacks.
The art and the scenes are definitely the best part of this game. Personal taste aside you will find a variety including insects, animated objects, tentacles and Mr. Bean's favorite stuffed toy. After seeing a scene, you are able to find them in a gallery.
The game has some room for improvement, but is passable. And if Insects and stuff like that do not disgust you, this here might be something for you to look into.
