This is a fun little game. This game is something you really can improve your self with! You probably start with 30-50 clicks, but after a couple of tries you notice how you get better and better, and soon you will rank Chu... mmm... . If you want to know what the highest rank is, you need to keep playing. ;)
Lights are lit one at the time and you are supposed to click on them IN THE SAME ORDER as they are lit. (Not always the one which is lit at the moment). For example, if the lights are lit in this order: Blue, Red, Purple, you are supposed to push the buttons in the same order (blue, red, purple). In the end when you are not fast enough, you have to use your memory, and use it fast!
You can use your mouse or q, w, e, r keys.
