Numpad Madness good game
This was a really fun game! Apart from epileptics not being able to play this, I wonder if red/green colorblind people would be able to see the numbers at all. I'd suggest putting in a time limit mode where the number would be displayed on the screen for an increasingly small period of time and then go on to the next number if you didn't type it in right away. All in all, you did a really good job on this, it's simple and fun!
