For such a simple game (just clicking squares), there's some real nice juice to it...the pings when clicking the buttons, the why they pop a little, and how the pings escalate each time you get one in succession made it feel really good to click the buttons, well done.
Honestly, I didn't read the game description and just jumped in. So when I first started, I was very tentative, wondering where this was going...and then wham! All the colors changed. I got a kick out of that.
I thought this was pretty clever, and a really interesting way to give a window into what being color blindness. I liked that you showed the name of the type of color blindness with each shift.
Well done!
