You definitely nailed the theme! It was nice to see a more puzzle-focused game here. The only part I struggled with figuring out was when it told me I had to use the yin/yang runes on the sol/moon portals, since they were white and black so I assume they were actually yin/yang portals instead.
I had a good time with it, even though I died a couple times in the combat section because I kept messing up the strafe and turn buttons. My biggest suggestion is that you speed up the text boxes, as they were a bit on the slow side. Also, you got some reflowing issue with how you animated the text boxes (it going to the next line mid word) which, assuming you're using TextMeshPro, you could have used the maxVisibleCharacters property to animate without that issue. Just a minor quibble.
Good work!
