v1.4.0
>>Update has
not
been cooking for 2 years, its been
delayed heavily by my other work
, various life factors such as horrible living conditions (shitty house, caring for landlady who has dementia), moving, getting covid, etc.<<
To start Mitsuki's story, fuck every girl, and then go to your room.
This is update 1/3, update 2/3 should be in the next 3 weeks with 3/3 coming a month or so after that.
Do not view this as an entire, single, update. View it more as a piece of a greater update, given the scope, time, and various other factors involved, I thought it'd be best to break up the single largest update yet into smaller pieces. This update is more of a. . .life pulse, the start of the main event, if you will.
The entire game is being updated sequentially, so, everything is liable to change.
This is MAINLY story based. Text, with placeholder backgrounds/sex/character art that WILL be updated VERY soon.

- most likely fixed the wife chasing you down (never experienced it)

Clarifications
- plant girls are just eyecandy until I figure out the sex-system more. I need feedback for if you guys like the sex-work and want to see it expanded enough to replace the current lobby-girl's screen.

Summarised from 20 written player reviews.
I love the concept of going on an ego trip with a big dick or a humiliation ritual with a small one but the execution is so bad and I have no idea what is going on half the time…
Realistically it's probably more of a 3 star but it's kind of endearing and I don't want to bring the rating down. I'm hoping this isn't entirely abandoned and the developer will eventually come back to it because there's definitely…
Humorous and cute, overall right now its an enjoyable if simple and short experience. Clearly this is still in development but I'm excited to see where the dev goes with this, its genuinely a unique and interesting little experience. Obviously…
