When I read your description, I'm mainly wondering why do you do the dumpster diving. What is the ultimate goal?
While there isn't a definite 'end', the ultimate goal of the game is to fill up your journal (find all the items possible). This can vary though depending on the person; some might want to be a completionist and do that, where others may just want to simply dumpster dive and do the loop of selling finds and accumulating as much money as possible.
I dumpster dive IRL and as a game dev I kept thinking about ways I could make it into a video game (because in real life it certainly feels like a game haha) so that's what this project is, just a gamified version of what myself and other dumpster divers do.
