Lots of fun until you spend two days fixing a bug, think it's fixed, only for there to be a loophole. xD
Game is updated, btw. But when I tested it, the 'spy on them' choice was in auto-saves so it might be there and you can just undo that choice if you want. Sorry for the frustration.
probably entirely redundant now, but i persisted with the old version. during the section where trying to go to the station says 'waiting for tetrine', you can go and spy again which leads to the softlock. but if you look at the boat first it's fine. just thought i report back on that in case it helps. but since you've updated, probably not :D
anyways, i finished! didn't realise how close to the end i was :D great stuff, i really liked it. love the way you composed scenes visually. gave me some inspiration for how i can approach some game design in the future. good luck with the jam!
