Yet Another Numbers Game

It's just a five-digit number - can't be that hard to guess, right?

Well thankfully you get clues when you fail miserably:
- If a digit you guessed is RED, it's nowhere to be found in the correct number, so pick a new one!
- If a digit you guessed is YELLOW, it's there somewhere, just in the wrong spot.
- If a digit you guessed is GREEN, it's in the right place, keep working on the others.

Just a simple little guessing game. It takes almost no time to play a round or two, so have fun.

TODO:
- Variable amount of digits.
- Save best score.
- Timed mode!
- Difficulty settings (would be harder if you couldn't see your previous guesses, huh?)
