(Japanese only version)
I am rating this after having played it entirely through in Japanese, which is honestly a testament to my enjoyment. I will definitely be replaying it with MTL to once again enjoy the title.
This is one of very few hentai games I enjoyed from start to finish. The art style is right up my alley, as are most of the scenes available. Aside from the art being high quality, there's also a wide range of variety that even includes futa on trap. You've tentacles, you've got monster girls, and you even have some regular(ish) girls in there, too. It's a mixing pot of high quality lewds that is almost certain to have something for you, lest you're only into the niche.
The gameplay isn't great enough that I would say it's enjoyable, but it's not bad at all. More importantly, it's not insufferable like most hentai games. Better still, it basically lets you cheat and become invincible early on. The game even makes it easy to get H-scenes despite being over powered, meaning you really can just enjoy the game as a whole.
The game does slow a lot towards the end, clearly trying to pad out the play time, which is honestly a shame. It doesn't ruin the experience, but it would be better without. Still, despite that, this is very much worth your time.
Great art, great style, trap protagonist, and good gameplay? Give it a try, it's worth it.
