This was fun and surprisingly deep in complexity! I could easily see people loving this; my biggest recommendations are a more drawn-out tutorial/introduction where you introduce all the features little by little instead of throwing them all at the player at the start.
I'd actually LOVE if the potions had effects that I could use as a player (more moves, affecting the board, etc) and therefore I had a little choice of whether to keep them for myself or to sell them.
I did notice that pieces sometimes overlapped with each other (especially runes overlapping other pieces, but also actual tiles overlapping other tiles that you only see when you try to move the top one of the "stack"). Also, I noticed that turning off all the sounds in the settings doesn't actually turn off all the sounds. ;)
