Find the shape of the indicated colour before the time runs out, but be careful not to touch any other shapes otherwise you will lose time.
Precision is vital but speed is important too, in fact, the faster you are at finding the shape, the more time you will gain. There are many different shapes and colours. Don't let them confuse you if you want to reach the last level of the game.
