0.3.0 Art Timelapses

Hello my MODIFIERS!!

What an update. Had to stay up until like 5am to get this update finished, but I really like how it turned out.

This time around, I tried to some some different techniques with the way I color my art.
Especially on the Bimbo MODIFICATIONS - where I tried to make the shadows a bit sharper, as well as add a "color terminator(?)" dividing the light and dark parts.

The Night Visit also was interesting to do, since I had never done a scene...

This update ended up being a big one - but finally I can announce that version 0.3.0 - The Bimbo update has reached the Polishing phase!!

I'm now working on adding all the sound effects, additional VFXs and testing everything out.

Status Update - Writing and Subliminals

Hello my MODDERS and MODIFIERS!!

It's weekend once again, so it's time for another status update!!

This will be a smaller post, since most of the gameplay changes I already shared on my previous post.
I'm still working on update 0.3.0, the art and code is mostly finished, so now I'm just working on putting everything together and writing the scenarios.
It's going well and I hope ...

0.3.0 Bimbo: WIP Set

Hello my MODIFIERS!!

It's time for another batch of WIPs!!
Pretty much finished with the code updates for version 0.3.0, so now I've been working on making all the necessary art assets, so that I can start writing the scenes.

The path will have 4 MODIFICATION steps - all paths have had this amount so far but this isn't a rule or anything... I just keep writing sequences of 4...?
The first 2 will be body focused (change hair color, ass expansion), while the l...

Today marks 1 month since MODIFICATION APP was first released!!

So much has happened since then, from a new update, surpassing 100 supporters, over 20k downloads!!

Thank you all who have supported me and allowed MODIFICATION APP development to continue!

I'm currently hard at work for update 0.3.0 - Bimbo.
However, this post will be a little different, since I want to share all of the quality of...

Paths, Progression and Polish

Hello my MODDERS and MODIFIERS!!

In this post, I want to talk a explain the plans for the paths and progression of MODIFICATION APP - as well as some QoL improvements that I'm working on for version 0.3.0 to better show the paths.

What are paths?

So paths are basically just a sequence of events that relate to a specific MODIFICATION.

As you might have seen, when you select the first Mind Control or the Breast Expansion MODIFICATION o...

Susie Bonus Sketch (and General Updates)

Hello my MODDERS and MODIFIERS!!

Yesterday I was watching some art tutorials and trying to practice some different body types I'm not as used to drawing, and ended doing this silly sketch which I thought was kinda cute, and yes, I'm very excited for Deltarune.
Gonna play the hell out of it this weekend.

General Updates

Today marks 3 weeks since MODIFICATION APP was first released!! Yes only 3 weeks!!

MOD APP 0.3.0 - Theme Vote

Hello my MODDERS and MODIFIERS!!

As I had mentioned before, whenever I release a new version of MODIFICATION APP, I want to do a theme vote, so I can know what you'd like to see me work on next!!

The next update might not always be what is voted on, but this allows me to know what to prioritize and start coming up with ideas for them!

This vote will run unti...

0.2.0 Art Timelapses

Hello my MODIFIERS!!

This new update was quite something.
Originally I expected to mostly just write text, maybe just a couple new expressions and a simple event.

And instead I went ahead and made completely different art for each MODIFICATION and even a simple animation for the event!
ClipStudio tells me this 3 timelapses were around 23h of work. Oh boy.

Every release I want to try and improve something specific with my art, this time I tried to figur...

MODIFICATION APP (0.2.0) - Supporter Release

The wait is over, it's time for the second content update for MODIFICATION APP!! Version 0.2.0 - Mind Control is now available!

Hello my MODDERS and MODIFIERS!!

The wait is over, it is time for the second content update for MODIFICATION APP!!

Originally this was gonna be a smaller update, since I thought Mind Control wouldn't require that much new art - however I had too much fun making this and I ended up with more art than 0.1.0!...

MOD APP 0.2.0 - Polishing Notice

Hello my MODDERS and MODIFIERS!!

I've been hard at work for version 0.2.0 - The Mind Control update, and I can finally announce we've reached the Polishing phase!!

What does this mean?
It means the content is all done, so I'm in the process of testing everything and giving the final touches!

And more importantly, this serves to announce that this update should be out THIS SUNDAY!!

0.2.0 Mind Control: WIP Set

Hello my MODIFIERS!!

I hope you're all having a good weekend, I'm still hard at work for version 0.2.0 - The Mind Control update!

Progress has been going smoothly. It seems spending the extra time during the development of 0.1.0 to have an actual framework really helps things go along better, without having to rewrite big chunks of code.

I already spoke a bit about the general idea for version 0.2.0 on 2025-05-25 22:27:46 +0000 UTC View Post

Status Update - Hypno Awareness

Hello my MODDERS and MODIFIERS!

It has been a week since version 0.1.0 has been released!!
(Well, it was one week yesterday night, but I think it's close enough)

Progress for version 0.2.0 - the Mind Control update - has been going smoothly.
I think I'm mostly done with the code side, so now I've been working on writing and doing the art.

As I had mention on my p...

Poster Illustrations

Hello my MODIFIERS!!

While playing you might have noticed on the player's room a small poster and - much more noticeable - the player's phone background.

Those were actually illustrations I did last year (posted on bluesky), and while making the game, I thought they made for good for decoration - at least better than putting a generic phone background and empty walls.

Star Transparency

Hello everyone!

This is a quick post just to inform you all that I now also have a SubscribeStar page.
I had created it a few days before 0.1.0's release, but the validation took a long time.
It's finally up.

This will not affect this patreon in any way, it's basically just an alternative for people who don't want to/can't use patreon and would like to support MODIFICATION APP.
The content posted, tiers and benefits will...

Status Update - Minigame and Milestones

Hello my MODDERS and MODIFIERS!!

It has been 4 days since version 0.1.0 was released - and the reactions I've gotten are so much more than I ever expected.

We were able to reach some amazing milestones

• Over 10k downloads on itch

• Over 50 Patreon members

I honestly never thought I would get this far, much less in such a short time!
Thank you guys so much!!

Well onto the status up...

MODIFICATION APP (0.1.1) - Lag Improvement

Hello everyone!!

I saw a comment saying that whenever they talked with Mia the lag on their laptop would spike.
I went to check it out, and truth be told - the outline shader on Mia was probably the most graphically intensive thing on the whole game.

Changelog

• Replaced Mia's outline shader that was too expensive on the GPU

• Fix misaligned boobs on BreastExpansion minigame

Next MODIFICATION: Mind Control

Hello my MODDERS and MODIFIERS!

With the public release of version 0.1.0, the reception has been a lot bigger than I ever expected!
Both on itchio and here!

In the future, after the public releases, I want to make a poll here with different MODIFICATION options so you guys can vote what you'd like to see next.
It won't mean that will 100% be the following update, but it will bump it to the top of my "todo" list!!

For update 0.2.0 however, since I had t...

Breast Expansion, Accidental Boobjob, New Expressions

Hello my MODIFIERS!

With this new update we finally have began the MODIFICATIONS!!

There was a lot of learning curve on how much was actually needed for a content update. And you'll definitely see that on the timelapses this time.

Like on the "Breast Expansion MODIFICATIONS" video where I only figure out how things should look around the 2m mark, because I kept getting annoyed at either the anatomy not looking right or the boobs beings too small.

MODIFICATION APP (0.1.0) - Breast Expansion

The first MODIFICATION is done! Starting off with Breast Expansion!

First MODIFICATION! This is the actual first content release for the game. 

With this I could finally have a feel on how much work goes into each part of the game (events, art, writing)....

Mia and Tightly Sprites

Hello my Modifiers!

Here is the first behind the scenes look at how MODIFICATION APP is being made.

For some additional behind the scenes information, ClipStudioPaint claims that the Mia sprite file has been worked on for over 15 hours.

This already is a big value, but considering I have copied and pasted this file so many times, I would guess the real value is probably closer to 30.
For a single sprite.

Goddamn.
