In short hentai zuma.

It's like Mirror with zuma gameplay, with similar UI, skills, items, stats system.
Comparing to mirror, it's far too easy, you got plenty of money each round, skill and item are not really important.
You got 5 girls with 1 protagonist. It has 1 big story unlike mirror and 2 "interactive" scenes for each girls.
The translation is understandable at least, voice acting in secs scene is bad, story is okayish.
It's perfect for the fellow degenerates that only aim for secs scenes. But if you also want better everything, go for mirror instead.
