As a 3D animated porn it's like a 9/10. As a "game" though, since this is ostensibly a gaming website, I'm basically rating a DVD scene select menu. The animation's top of its class in terms of 3D hentai, especially for 2016, and the voice acting's great. I know literally nothing about Liru as a character, and from what I hear apparently the characterization here has absolutely nothing to do with how she is in Renkin san-kyuu Magical, but nevertheless the voice actress does a great job portraying the genki tomboyishness of...the creator's idealization of the character, I suppose. The few background tracks featured are actually pretty nice and relaxing, beautiful even. I especially like the guitar in the title theme. Also, I think the game has some sort of microphone feature, where you can literally shout the responses instead of clicking on them? I can't even begin to comprehend the level of horny you'd have to be to use that feature, but props to you if you do.
