Even thought seems to get chaotic pretty soon in the game, the music kept me pretty chill, I had to redo the second level couple times because its hard to understand visually which gem fits on which ring, (not sure how to solve the problem) I also felt the camera could follow you better to make sure you are able to pickup jewels and drop the rings more easily (this might a conscious design choice).
Overall a good entry to the jam, fits the thematic like a perfect ruby ring ;)
