Web Page Navigation

Based on the previous idea that I want to make a music game, I still think trigger buttons can be the best option. My plan is to first divide the whole web pages into 4 tracks, which are very similar to the settings in the AU. And then defining each button as a piece of sound. If the viewer successfully uses “1,2,3,4” on the keyboard to trigger that function, a certain sound will be made and one point will be recorded. In order to make sure that viewers press the keyboard at an appropriate time. I decide to use the surface like this.It might require some calculation to find the proper timing point for the brick to fall from the top of the page. And the viewers should press the keyboard when the brick reaches the bottom of the page. So together, if viewers manage to trigger every function, they could enjoy the whole rhythm. Otherwise, a single missing will result in the incompleteness of the melody.
