An additional track that was intended to be played on Cave Story on its early versions.
An alternative version is included, where it uses different drum samples heard in previous versions of OrgView. (popularly named by Beta Drums by the community)
If you want to use the alternative version of the drums, open the text file and change the Beta_Drums define to 1.
03/24 Update: An echoing effect was added every time the open hi-hat plays, to make it sound less cut-off.
