A little underrated game by the other reviewer.
First of all, the combat is almost non-existence. It is far too easy and Hscene being tied to losing in battle is not compiling way to experience the events.
However, that is pretty much the only real complaint of quality here.
There are plenty to enjoy in this small game:
The plot is simple yet has an interesting twist to it. The secret is even hiding in plain sight. There is even little foreshadowing as to the plot twist in the game before the finale.
It won't blow your mind, nor it will give you a hot blooded fight that RPG should have, but it is serviceable to holds the player attention throughout the game until the very end.
The hentai scenario with each student(and a teacher) is rather creative, erotic, and keep you guessing what is going to happen next.
To just spoil one scenario . Shota, the cousin of Natsuha the protagonist, will be trapped in a house. There is no way out. Just you and her. There is a mirror that seemingly showing their near future. Each future is a erotic situation. Now Shota keep trying to deny and avoid every erotic situation as shown in the mirror. However, he keeps failing spectacularly despite planning beforehand to counter each predicted future. Well, and this isnt even the end to this one particular H scenerio. It has one small, but significant twist to it before ending this particular H scenario.
Finally, Natsuha is beautifully designed and drawn. She looks hot,sporty and fitting for a PE teacher that isn't too obnoxiously or too fantastically designed. The game has a good variety of hairstyles, clothing, and facial expression to go along to keep each H-scenerio interesting.
In summary, It is a very short game that is just barely 1hr if you just beat everything up and clear the game. However, you will be experiencing the game at its weakest point. The game has no money, leveling, or interesting combat. It excels in its own rights for being simple, engaging H scenario, and overarching plot with a neat little plot twist.
Rating: Give it a try and enjoy the erotic rather than combat. You will be pleased and have a fun little bite-sized erotic experience. Especially if you have any interest in the design of the heroine, give it a go.
