This is awesome! Super polished for a jam game. I'm really into the backtracking through old areas in order to do new things. Really adds to the atmosphere compared to if it were just a linear set of levels. Also really liked the design of the shrine things, lots of character.
I ended up getting stuck at the part underground. Looks like one of the platforms disappeared for some reason. Not sure if that was a bug or if I'm too dumb to figure it out.
Either way such a great entry!
