Hey, thank you so much for your detailed and thoughtful comment! (and sorry for the late reply...)
I really hope to get around to continue working on this game someday, especially to deliver the message of the game in a more elegant way. I can also understand the interpretation of the graveyard theme, that's actually something one of my playtesters also felt strongly, and the visuals clearly point in that direction. I actually like this as a metaphor, but should probably try to avoid evoking such mixed feelings between the perceived gameplay and ending, like you described. Will have to think about that :)
