Being a game made in 15 minutes its great stuff man ;) I like it, btw if you can keep doing games to test reaction skills and other it would be nice.!!
Cheers.!

Pretty cool

I finished it so easily within the 4th try

boring

i did it like 15 times and got it spot on, no times for a reaction test means just a flashing screen

it took forever

i dont even know how many tries it took lol but this had no effort put into it so ill give you a 5

Needs something to keep track and randomize flash.

Clicked a couple times just to practice my own reaction times, but with the set time for the red flash, within three attempts I hit it exactly. It's not a reaction test unless it's unpredictable. Also, if there was a function to have it reveal how many nanoseconds off you were from clicking at the right time, it would serve even better as a test. It's alright for a 15 minute project.
