Updated on June 16th 2026, what's new in version 0.2.1?
The Fantasy storyline continues with new story content involving Pat and the mysterious ruins. Allison receives a new animated camgirl show, the first scene animated with Moho. The update also improves visuals, including a redesigned photo button and a new 3D cobblestone road, plus quality of life improvements for stencil creation.
📢 Version 0.2.1 Released!
The second act of the Fantasy arc is here! 🏰
After visiting the mysterious structure on the hill, Leo's curiosity gets the better of him. A return trip to the ruins leads to a visit from Pat at the tattoo parlor, where a few secrets are finally revealed. Plus, she becomes a customer herself.
🎥 Allison's second camgirl webshow has also been added. You can access it through the Self Service app on Leo's tablet. This scene marks the first animation in the game created with Moho, a professional animation package used in major animated productions.

⚠️ Save System Change
The save directory has been renamed to "BTAS" so both the SFW and NSFW versions can share saves going forward.
Unfortunately, older saves from previous versions are not compatible with this release. 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

- Anal with Sakura - this is just added to her HumBull scene. Vanilla sex is available as well.
