Hello,
I've been looking to add something new to my brain training repertoire, but wanted something that specifically targeted mental math. I figured because a lot of mental math involves working memory, I could kill two birds with one stone. 

And so I built.... Turd Turf(https://turdturf.app). Its a **VERY** high pressure game where you have to solve math questions in quick succession, or else The Evil Man will defecate in your beautiful garden. I have been using it everyday for about a week now, and my ability to do mental math has increased significantly. 

If you want to go REALLY spicy(and have the stomach for it), play with the sound on. 

I would love your feedback!

Funny game. I would add also some optional sound into background that will put even more pressure on you and also numbers should come from different angles

Thanks! The sound button is at the bottom right corner of the screen(see attached screenshot). Please wear your earphones if you play with the sound on, or prepare to be embarrassed.

I made a similar thing which just displays scat porn images every time you do a mistake and whenever you get a question correctly it shows a genre of porn you like and set in settings

Sorry but my app is not even in the same universe of degeneracy as yours lol.

as a feedback you should maybe allow people to choose the level they want when they come back to the game, because you can't choose the level of your first game, and i like to start slow :)

Hey, I just wanted to say I really enjoy the game — it’s genuinely a great concept.

I did notice a small bug: when the bar gets very red and the character “poops everywhere,” the results page sometimes doesn’t show, and I have to refresh. That makes it hard to review mistakes.

Also, just a small personal observation (feel free to ignore of course): I feel like the game is super powerful for focus when the math is still manageable. For me, around level 5 it feels perfect :I’m slightly challenged but still able to stay focused despite the distractions.

But once the math gets harder, I start missing too much, and it feels like my working memory gets overloaded, so I lose that “focus under pressure” effect.

I was wondering if maybe keeping the math simpler (or letting players choose math difficulty separately from distractions) could preserve that really strong focus-training aspect you’ve built.

Either way, really cool idea — I’m enjoying it a lot!
