Nice game! A lot different skills you can use. It would be helpful if you could see some kind of summary of them in the battle itself, or if you could unlock more as you go it wouldn't be as overwhelming.
Actions determined by a die roll is fine, but maybe RNG could have been used somewhere else as well.
Battle animations and effects were smooth. Perhaps giving more information about the enemies and how many there are going to be (per wave?) would be a great addition.
Good job, lot of content for a jam game!
