Thank you!
I'm glad you liked the spirit's movement, that was where I started development and wanted to get the right feel across. I wasn't sure if the overshooting was too much and it varies based on how far it has to move, but I'm glad it was at least interesting.
I would like each button activated to have a sound, and when the vortexes are placed and grow. And I agree, possibly for collecting, though it would have to be very subtle to not become overbearing. Hm, maybe a very small sound just when the spirit collects the mana . . .
