UvC app for iPhone and iPad

UvC is a simple yet a mentally challenging game.
Pick from Red, Yellow, Blue or Green each level. Only one will let you move on. Get it right and advance, wrong and back to the beginning you go. Once you pass the level the color will lock in and not change.

With 500 levels, can you remember them all?

Modes:
Casual - Pick at your leisure
Timed - Well give you the color to pick, How many can you get before the timer runs out
Hard Mode - Only 3 seconds to pick. Once the timer hits 0 you go back to level 1
