Well, this isn't really much of a game. Just a gallery with extra steps tbh. I picked it up because the screenshots about how boobs were mauled looked hot, and the last game with huge boobs I played didn't do them justice. This guy's art is janky, but man, he goes hard on the boob mauling, bouncing, flopping and all that good stuff you'd want to see when huge-ass boobs are involved. Wish more artists did what this guy did here.
That said, aside from that, there's literally no worth in the game. The story is basically non-existent. The gameplay is boring if you don't opt out of it from the get go. The sex-scenes are just ok aside from the visuals, not to mention that not everyone is likely to be into watching what amounts to living dolls getting fucked.
Still, an ok time-waster if you're really into the visuals or have a particular itch to scratch. Otherwise, an easy skip to be sure. Debatable use of money if you choose to spend it on this thing. You're paying for the art more than anything else.
On a different note, I really do wonder what tags this game has to end up hidden on dlsite... Too lazy to VPN to check.
