Looks like it’s only possible to score any points by pressing a key at random times. The way the game logic works (as far as I can tell from a very cursory look), is it detects a keypress only
after the color of the screen changes. I even deliberately slowed emulation down to ten percent and pressed and held a key as soon as the color of the screen matched that of the border. The game only acknowledged the keypress on the
next color change.
Hint: Since colors change randomly, sometimes the same color is displayed twice in a row (possibly even more). Perhaps, once you press a key when the colors match the first time, if the next color happens to be the same as well, you’ll get lucky.
The game truly lives up to the competition’s name.
