Designing this game has been such an interesting case study in how hard it is to discourage RPG habits without totally hamstringing the design space. Like the tapestry fragments encourage something they're not really MEANT to but I also wouldn't want to lose what they do narratively so ????
You definitely don't have to collect 200 mosaic tiles to get the Super Secret Ending though, haha.
I may just add an autosave feature to a future patch, since so many people seem to be playing this for... well, much longer stretches than I really expected!
