Ah, right, yeah there's no feedback to the player at all so that's on me :D I'm glad you got it working!
I don't have any plans for this after the jam. There were a few minor things left on my todo list and the core gameplay is in place, so it's pretty much done except for UI, polish and bugfixes. I wanted the focus to be a short story and I don't really feel like expanding it much to turn it into a "full" game. The duality mechanic works because it is a short game, I think. If the game takes hours to complete then there's not really a point in trying to balance the alignment, and one of the two items will fall off hard for 95% of the game. And changing things up too much will turn it into a different game...
Maybe next time if I create something more open ended or with more progression, there's a way to squeeze more content with purpose in there for a post-jam game
