Even with tempered expectations (as the circle's last game was about as good as hentai games are allowed to get), I can't help but to feel disappointed in this one. The pixel animations are some of the circle's best, although with so few enemies only a few of them were particuarly fun. The gameplay loop is repetitive as enemies are too simple, and there's no clever game design where they mix up enemies of different types in a way that would make the gameplay from room to room room any different. I think one of my biggest frustrations is how hard it is to stay above 1hp with all the projectile spam, but how easy it is to not drop below 1hp by breaking out of grapples. I think Ethereal Legion's system of being helpless when grappled but being able to be saved by allies would have made sense here as the ally characters play a big focus, although as currently implemented, not in any particuarly fun way.
It's still not bad for a hentai game. Most hentai games feel like they were made by someone who draws hentai and not someone who develops games, and while this has some pretty questionable design decisions it still has a level of care above those. It's just hard to look at it in a vacuum, at least for me.
