It is a kinda good game, but frustrating for an adult game:
1 - There is no gallery
2 - It's kinda hard for a hentai game, even in the casual difficulty
3 - It is a wave shooter game, but there are no permanent upgrades, addons, or leveling up , Which are the trademark of this type of game!
4 - The enemies have instant reaction, if you jump to a platform, they jump at the same time you are jumping, for example.
So it is a very hard hentai game with no gallery and (SPOILER) a Very frustrating ending. I do not
While I don't think the five dollars I spent was wasted, I do think the developer could at least put out a demo version.
