Can there be multiple endings... here me out getting upgrades im totally guess can be based off items or fighting back like you know eating them?
More than 1 ending is currently planned, but it's still loose in terms of what these will be; Moreso has to do with NPC relations than anything else, which should effectively boil down to hunting for some items around the map; This is also to incentivize going after some optional bosses and finding a hidden location or two.
