Click any picture. Then press the key displayed. This is an alpha, so I will update the game as time goes on. I remixed this from the DOORS soundtrack project, so everything will be different, other than the thumbnail, of course.
The four markers near Purple Marker and Dark Markery represent the four markers I need in the actual game. Edit: I have all the markers now Thumbnail is by me, as always when a cool thumbnail is on my project.
