The art is amazing!!
The mechanic has potential, it just needs a little push.
I have a few suggestion:
- highlight the dice that you can match. To progress bar in the bottom is fine, but does not give enough feedback (It can be buggy at times).
- You could allow the player to execute spells with fewer dice, and the punishment being a less powerful spell, instead of losing mana. It would give the player more options.
Keep up the good work!!
