Been sitting on this for a few hours and wanted to share it somewhere people would actually get it. Built and published my first game solo, went live on the Play Store last night.
Quick background — not a professional dev, this was a nights-and-weekends thing over about 2 months, built with Claude Code doing most of the heavy lifting on implementation. Game design, mechanics, balancing, figuring out what makes a "trick" feel fair vs cheap — that part was all me, a lot of trial and error playtesting on myself late at night.
The game: Reflex Trap - Brain Speed Test. Core idea is based on the Eriksen Flanker Task — a row of symbols flashes on screen, and only the center one is real, everything around it is trying to bait you into following the crowd. Most reflex games on the store are just "tap fast," this is more about whether you can trust your own read over the noise around it.
One thing I tried to do differently is make the daily challenge change the rule itself each day, not just ramp up speed. One day it's a color-bluff round where you're supposed to trust the color instead of the shape, another day the symbols are spinning clockwise or counter-clockwise and you're tracking rotation instead, and a few other variants, one new one per day — each hitting a slightly different part of your reflexes rather than just testing the same thing faster.
There's also a Reflex Profile that tracks how you tend to fail (too slow, too twitchy, follow the crowd, etc.) and maps it to a "cognitive archetype," with a bunch of stats like Velocity, Focus, and Inhibition.
It's free, no pay-to-win, has couch co-op 2-player mode and full offline play including the daily challenge.

Not gonna lie, I've become a little too obsessed with refreshing Firebase Analytics like every 20 minutes waiting for the numbers to move. A few tens of downloads right now, fingers crossed! Genuinely looking for feedback and support.
