Review is for v0.01b
As a huge JAV enjoyer, I'm extremely excited for how this is going to pan out, but as it is now, I cannot recommend it.
The game is based around grinding, which the creator has confirmed in the comments, but there just isn't enough (right now) to justify the grind. For games that have crazy amounts of grinding, there has to be a payoff for that grind, and right now, there just isn't enough in this game.
The scenes are great, the story is good, the game play appears to be pretty solid, there just isn't enough lewd content yet.
On a personal note, I hate rating new games lowly due to a lack of content, but at the same time, I can't give it a higher rating based on something that may or may not happen.
Edit for v0.06b: The dev has made some really great changes. The game feels a lot less grindy and a lot more rewarding. There are a medium about of errors and blank pages that need worked out, but with the back button they aren't really an issue. Upped the rating to four stars for now.
