TimeAttack Mode:

Timer is set to 30 seconds, and you have to get as many XP points as you can before it reaches 0. One mistake and it's GAME OVER.

Classic Mode:

In classic mode you start with 3 lives. Color name will change if you're too slow or you tap wrong button you will lose 1 life. In the beginning color name changes every 6 seconds. The longer you play, the faster it will change.

You start out with 8 buttons in their usual order, but every 10 seconds they will randomly change places. Same as in classic mode, you have 3 lifes, and color name changes but more frequently than in classic mode.
