Reading the feedback on this so far it seems like the general consensus is that people might enjoy such content but should perhaps focus on finishing the area/most of the game before diving into it.
In terms of combining Game Over elements for Bad Ends, that would probably be more saved for much later and reminds me of another game that featured that originally. That sort of playable Game Over is a little outside what I was thinking but is certainly something I will keep in mind. Thanks!
