Felt like a mixture of an auto brawler like RAID and Mario party.
I actually had fun and found myself more engaged than I probably should be about a dice being rolled.
The only thing I was missing was a bit of player interaction. You just click the dice once and everything happens automatically. I think I would have liked it even more if I press the dice-button before attacking and blocking.
Right now it's also pretty much random if you beat the boss, since you need to hit as many upgrade field before and get as many levels as possible.
Have you considered adding choosable upgrades? I think that would have added more personality to each run.
But overall I really liked your game.
