A whole story and LORE plus all these mechanics made in 72 hours is WILD, really impressive stuff!! Took me a bit to figure out but once I did it felt very satisfying to keep trying to get all the sigils. Really clear UI and nice graphics, too.
One small remark maybe is that I found myself never using the Scry spell as it only revealed one tile and healing ended up being the more useful scenario. I think if it revealed more tiles or a certain path like the crystals I would've used it more. But that's only a nitpick, great job!!
