About

Leo Pujols moves to the historic town of Las Nalgas to open a butthole tattoo parlor, which is exactly as controversial as it sounds. Plenty of locals see him as a corrupting influence, and a group called Collective S.H.A.R.T. is organizing to make sure his stay is short.

A council election, an Arts & Culture Festival, and an unsolved attack all churn in the background while Leo tries to keep his shop open. Your choices steer how the town, and Leo, come out the other side.

Days are spent talking to residents, checking the news, and swiping through the HumBull dating service to hook up with local wives and girlfriends when the opportunity arises. The actual craft comes down to drawing tattoos on butts, stencil by stencil, with the client's rear end as the canvas.

Changelog

v. 0.2.2a

This is not the monthly update, just a small tech update to fix bugs that broke stencil positioning in the last one. This version also allows you to select all the tattoo stencils you want to use at the same time and drag and drop them all at the same time, making it a lot easier to adjust your vision!
v. 0.2.2
Become a test subject at the re-education clinic downtown. You'll formally meet Farrah, a semi-burned out educator who happens to be one of your protesters. You can access this scene by selecting the flyer on the bench once the protest starts. (Or use the New Scenes Only Mode! More on that below)
Farrah visits the shop.
Revised Ice Cream scene with Rosa.
Restructured game logic: Before, characters showed up to the parlor on specific days. Now, most of them are triggered by specific choices of actions. For example, to get Rosa to show up, in the revised ice cream scene, Leo has to order an ice cream sandwich from her, which will...peak her interest. And Cass will not show unless you attend her rally and make a particular choice.
Stats! Leo's stats now include Brand Awareness, money, and Strength! This should help make things a little clearer. When you trigger a character's arrival for example, Leo receives a brand awareness token. When a character comes into the parlor for a tattoo, a brand awareness token is spent. (Maybe it should have a different name instead of brand awareness now, hmm.) You might be able to guess how to build the strength stat (the weights in the shop). At the moment there is not use for strength, but there will be!
5 new stencils including such timeless masterpieces as the Mona Lisa and The Scream!
New Scenes Only mode: Building this was a helpful step toward having a proper gallery of scenes. It'll jump you to new stuff so you don't have to replay everything.
Fixed:
The election day countdown wasn't working before. For any fellow RenPy users, I'll have you know sometimes changing game states within a screen just doesn't work. I simply had to move some code into a label. If only all debugging was so easy.
Known Issues:
In the process of revamping the tattoo system, it got temporarily worse! It seems to be okay as long as you drag a tattoo stencil before picking up the tool., meaning don't make rotation or scale your last action before tatting. Multiple tats with rotation might not work. Ah! It's embarrassing, but it should be all good and much better by the next update
I haven't fixed the Mac version bug during tattoo sessions.
Adding custom tattoos using PNGs still doesn't work.

v.0.2.1

The second act of the fantasy arc is here. After visiting the mysterious structure on the hill, and attempting to go there a second time even though it's just ruins, Pat will give a visit to the tattoo parlor and reveal a secret or two. Plus she patronizes the shop.
Allison's second camgirl webshow. In case you aren't aware, you access her show from the selfservice app on Leo's tablet. This marks the first animation in the game that I've used Moho to animate. Moho is a professional animation software that has been used to make a bunch of Oscar-nominated films. It's been a bit of work getting the hang of it, but I'm liking it so far.
The take a photo button has had a glow up.
Las Nalgas' cobblestone road! I'm probably more excited about this one than anybody else. The old cobblstone road was just a perspective warped image. Now it's actually 3D modeled.
Fixed:
Not exactly a fix but a change is that I made the default brush size much bigger for working on the stencils. I imagine most players want to do that part quickly and aren't trying to be precise. You can still choose a smaller nib size if you do need precision, however.

v.0.2.0

First Fantasy genre scene - after selecting Fantasy at the library, the hyper palace becomes available to select as an afternoon activity. Setting this up took awhile because the hyper palace (plus ruins) were 3D modeled in Blender and I'm not much of an architect but hey I think it turned out pretty well.
RPG Elements - Brand awareness and money are now tracked, making it more clear when you are paid and how much you need to make rent.
5 new tattoo stencils (53 in total)
NOTE: The save directory has been changed to "BTAS". I realized it needed to be a name that works for both the NSFW and the SFW versions of the game, so that if someone who has started the SFW version wants to upgrade, they can continue their playthrough. Unfortunately, that means that this version won't play your old saves. Sorry about that.

v0.1.9

Multi-Tattoo Stencils - Mix and match tattoo stencils to create an epic bootyscape.
Modding - You can now easily add characters to the game. I will dedicate an entire post to this process in the next day or two. But if you can't wait, there are instructions in the txt file of the mods folder and an empty background attached to this post to play with.
Tattoo Session UI aesthetic upgrade
Tattoo Stencil Categories - Better organization of stencils
Animation - Cassandra's political rally is a lot more fun now, with a simple little hand-drawn animation of her front-tied shirt coming untied. These are the kind of animations I hope to have the game jam packed with eventually,
Nib Sizes - One more tattoo session upgrade - You can now change the size of your tattoo nib. So if you want to go fast, grab the 15M; or go for the 3RL if you're trying to be precise. (This is in stencil mode only; sorry freehand mode)
5 new stencils (48 total)
Fixed:
Nib size use to scale with the stencil scale which resulted in strange results like the tiniest line if the stencil was scaled way down. This shouldn't be a problem anymore.
Game Over Bug - In v 0.1.8 my dumbass didn't test the game over screen and what was supposed to go to the menu in fact did not do that. It should work now.

v0.1.8

KTLN reporter, Naya Cervantes, enters the tattoo parlor. She wants another interview but the only way she's gonna get it is if she gets a tattoo!
Randos! The random customer generator is in effect on some days. The first one comes in on day 4 (assuming you didn't compromise on your butthole business and also rejected Allison's cash).
Tattoo Stencil Rotation! Finally! It's been requested for a bit. It sounds easily. And...actually it was kind of easy once I realized what was screwing the whole thing up.
The first Game Over Screen! If business doesn't pick up, Leo can't pay rent and we get the game's first game over screen. How do you make sure business does pick up? Hint: Don't compromise and refuse Allison's money.
A lewder interview with neighborhood council candidate, Cassandra. This interview is shown when Leo watches the KTLN app. I've added just a bit of spice to it.
Other scenes including:
Rita coming to collect rent
Officer Montez coming to the parlor because of complaints of indecency
A press conference with current neighborhood council president, Francesca Campos
10 new tattoo stencils (37 in total)
Mac Version
Fixed
If you're skipping when you take the photo of your tattoo, it shouldn't take a photo of the wrong screen anymore

v0.1.7

2nd HumBull scene with Rosa (maybe she'll send you a pic of her lounging in the quad)
Anal with Sakura - this is just added to her HumBull scene. Vanilla sex is available as well.
2 "random" customers interspersed between the plot-related ones (they aren't really random yet but with any luck they will be by my next update)
6 new celestial themed stencils
Leo can now workout in the afternoons
Fixed
purple stencil no longer appears in photo
Allison's tattoo positioning during cam show is corrected

v0.1.6
