I painstakingly made an entire flowchart to describe the method to get every tape and every ending. I don't know what part of me thought this was a good way to spend 2 hours, but here I am.

Here's a Google Drive link to the PDF: https://drive.google.com/file/d/1WcyYoWUqOztej1Sop60P2Sf27sxnX_Ir/view?usp=sharing

Please let me know if I made any errors. Also thinking of making this a page on the Wiki, so any admins let me know if that's a good idea.

Hope this helps people get endings easier than ever! ^^
