The game makes a simple yet interesting and pleasant use of the dice premise.
The progression is linear, intuitive and the experience smooth while presenting the player with an increasing level of chalenge.
Personally I'd suggest the dice abilities to be able to be draged and droped on the enemies or the player which i think would smothen the gameplay since thle player would only need to click once, speeding the player round.
I found no bugs while playing, the game has a polished impression.
I'll not comment too elaborately on the art since it says that it was not done by you, but think that it was well chosen, presents itself consistently and is properly assignd to the enemy tipes througout the game.
It was a good experience, good work.
