Why even bother at this point?
Like 3/4 of the game is some really fun exploration/collection/platforming. The abrupt ending because of budget and/or deadline was super obvious, but as it is, it was worth putting the time into getting basically all the cores for me. Actually having a more polished/finished version of it out there means a much better game, and there isn't an excess of games that hit on this blend of styles.
Plus chances are they're doing a wider PC release and a new retail package, so it's easier to market a re-launch like that.
