Hey, thanks for playing my other games, hope you liked em:) haha I play it quite a lot on mobile too, according to my stats I've played 219 times (not including all the testing I did before the proper release!)
That animation you made is amazing, I love it! It's like if Gun Rounds was a horror game haha I like the atmosphere you've created:) As far as the mythical third color goes, that is in fact a glitch created by the human brain! The button is shaking back and forth too quickly for the eye to track, but if you watched it frame by frame, you wouldn't see a third color!
