Thank you so much for checking it out! As per usual, my ambition is far too great for a game jam game making the mechanic far too complex for such a short project.
That said, if you happen to give it another shot, bet sure to click on the statues in the starting room to collect the Sun and Moon runes which give you access to spells that protect you in the labyrinth: The light spell protects you in the dark portal and the shade spell protects you in the light portal.
There is also a map spell (Harmony -> Sun) or (Harmony -> Moon) which will allow you to get through the labyrinth much easier and on to the next two sections (Body and Mind temples).
