Most of the stuff surrounding the actual boss fight was added lastly for context, though that was our idea in the beginning. I get how pathing can feel a bit weird though. The original idea was that there would be multiple boss battles before reaching the end, but programming those were a bit more than we could do for this jam's duration. Out of curiosity, did you get the finishing popup after defeating the boss? We hoped that we could make more of a little scene there explaining what happened afterwards, but sadly didn't have the time. If it didn't pop up for you, i dont know what went wrong lol, but no you are not supposed to be able to go back. Thanks for playing though, and thanks a lot for the feedback!
