This game could have been much better, the art is amazing and seems very polished, but it took a very bad decision, been short on purpose.
The Mc goes to a camp with her soldier companions for 5 days. You can choose the lewd events you want to do in the 5 days. After the five days, you get to choose an ending. Sounds great, but without any gameplay mechanics, the 5 days pass very quickly. You can't feel any corruption or development. In fact, there is not a good reason for Mc to corrupt herself in the first place.
You can unlock everything in the end, but that takes the fun out of the game in the end, so it is more like a collection of images using an RPG editor.
