About this game

Size Me Up is a Klein Voimond Ren'Py simulator parody built around a single concept: compare your weiner to fictional girls. The dev keeps the pitch deliberately tight.

The 2DCG and AI CG carry the cast and content threads pregnancy outcomes, animated scenes, big-tit character work, character creation depth, futa/trans, internal-view, interracial scenes, male protagonist core, monster girl roster, parody beats, and the very specific niche the title openly stakes out.

A niche-focused parody that knows exactly what its audience signed up for.

Installation
1. Extract and run.
Developer Notes
Art and "animations" are still kind of rough so as this project progresses, updates will be made. Placeholder assets currently exist as well but I feel they're not too intrusive so, for the time being, they will remain.

Pregnancy:

1. The game has a time system which goes all the way up to a year

2. Each girl has a specific fertility period, in which they can only get pregnant during a certain window of time.

3. I've simplified it to be only a set number of days within each month. So for one girl, it might be on days 11-14, and another it might be on days 20-21.

4. Each girl will announce to the player that they're ovulating and that "its dangerous" etc.

5. Each girl has a fertility level, and the player has a virility score. Once you deposit cum inside their womb, a check is run at the end of each day comparing both the amount of cum, your and her virility, against a base pass or fail depending on the girl. If the number is greater than the pass/fail stat, she will announce the pregnancy to you at the end of the day (hopefully, unless I borked the code and it skips the first time, in which you'll be notified about the birth once the gestation period has finished. )

Changelog

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.
v1.3.5
Simple bugfix patch - removed experimental sex from mitsuki - most likely fixed the wife chasing you down (never experienced it) - fixed the Avarice/Average scene - fixed most of the bugs presented by user takou33 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. - wife doesn't do anything just yet (except apparently lock you down [its like poetry]) - bar is still just a stand in - stat screen isn't a thing just yet
v1.3.4
-New art -Combat -Girls can move -More events -Unfinished art! -More character creation! -New sex work system -Its janky as fuck -You'll probably crash! -Save often. -And so much more.
v1.2.4
- Can now skip shower scene by leaving at the first time.
v1.2.3
-Minor (technically major but whatever) fixes. -Pregnancy should work now. That means, there shouldnt be anymore problems with only one person saying something, or someone overriding another, or Tristana taking everyone's pregnancies for her own. -Fixed the error with Mitsuki appearing in the store despite it saying she wasn't there -Fixed minor graphics error on sleep sex scene expunged filtration port -Updated penis measurements, no longer can you make a 0 inch penis -Updated height for more appropriate average heights, no longer can you be 0 inches tall
v1.2.2
-Minor updates to fix asset issues and save issues
