Since release, we've noticed a lot of valid criticism regarding a very tough puzzle in the "Water Cave" area of the game. After talking with the developer, we thought, who better to ask about the area than the heroines of the game? Let's see what they have to say...
We will be releasing a patch within the next few coming days that will clarify this further in-game, as the current hint is very ambiguous. We apologize for any trouble this may have caused players.
On a separate note, for those looking for an uncensor patch for the CGs, we're currently looking into providing one in the near future. We will post another update once we have more news about this.
