The dice stealing mechanics is very nice and original twist on dicebuilding game.
The pixelart is nice and all visuals sticks together very well. The pixelated text is maybe a little hard to read, but I understand its used for the united visual identity.
Some BG music would be nice.
I like the potential synegies when building a spell you want to cast, it just felt that the element aspect dice could be stronger than +1 effect (especially on higher rarities).
I guess overall I was little confused on the whole counter-element tactics and even afte beating the game I am not suer if I understood it coectly.
It was hard for me to decipher that these numbers in description are number of relevant faces on a dice.
There might be a little bug, where sometimes the elemental dice showed wrong name (eg. dice with ice icon and description had Water in name).
The escape dice felt kind of like cheating. It was much simpler to use it rather than fighting the mages. But maybe I was just lucky to get it most of the time.
Even with notes above, I really enjoyed the game.
Nice job!
