You guitar players will probably like this scene because it tests how fast you can alternately tap two of your four fingers on either hand. Instructions are in the scene. There are a lot of things to point out about this scene, and so I made two different versions of the instructions: One that is detailed with a lot of text, and the other that is a little more simplified. You can select which one you want by clicking on a selector button.

Let me know how you like it, and if you find any problems (bugs) or if you have suggestions to improve it. Thanks!
