Really cool game concept, enjoyed my time.

It's a dice game where you roll dices to defeat enemies, you can boost dices roll speed, extra damage and number of dices rolled each time, some dices have differences but not much to make them unique.

My advice for a full game would be to make the dices more unique, for example the D4, remove it's extra damage but add more to it's speed. For water you could remove the extra damage and add it to number of dies rolled, fire could have more extra damage, earth could have a single dice but with double, triple and quad chance damage.

Those are just small ideas, there's many possibilities, thank you for making this game.
