I love this game, its refreshing to find an AVN that has effort and life put into it. The characters seem well written, the art style is unique and vibrant, and the MC isn't a complete jackass like most of these games.
The card game works well enough, and its easy to cheese the hell out of it if the mechanic doesn't interest you.
I'd love to see the success of the business incorporated a bit more into the player's actions (have dialogue options/story branches where the MC could offer to use money as an aide if there is enough in the bank, or have the company evolve into a force of good) because being able to rack up a couple hundred thousand in a few days without any real benefit for it feels empty. Or maybe just showing more of the girls' side of the business in the story development, I like the dynamic of the characters being a team and growing closer, so seeing more of the team side of things would be cool.
