First, let me say I like the game overall. Nice characters and the story is funny. I would strongly suggest, as I sense English is not your mother tongue or your forte, to stick the entire script into a proofreader. There are a lot of typos, and grammatical errors, with some missing spaces between words at times. It'll improve the quality and immersion of the game A LOT.
And my last comment with a sincere request. I am still playing through the first game, v0.65, so all of what I said above is regarding this. I hope you do not abandon, or not improve even the base game, only focusing on the sequel. Unless that picks up the story in a logical manner. Onto my request: Is there a way to MURDER Maiko? Preferably in a very brutal way. In all my gaming years I have not seen a more disgusting character than her, and I am surprised you've even added such a piece of shit to the game. Let's just say that, for a sex game, the part with Maiko in the basement at the start of part 5 or 6, not sure, left me limp as fuck. She disgusts me beyond anything. Such people IRL should be butchered and disfigured in a most gruesome manner. Please consider it. Unless such an option already exists, in which case, God bless you!
