This is one of my early experiments with HTML5 elements. I espescially wanted to know at that time, how far I can come with HTML5-Audio. Graphics are on a canvas and it is using HTML5 audio.
This game was made without mobile in mind, so it is probably only well playable on devices with a mouse and a big enough display.
Simply click on the shapes in the order how they were played before you.
As soon as you hit the wrong shape, game over will appear.
There is no real win condition here. Simply try to get a higher score as the last time you played.
