Nice sfx!
And the "H.E.A.V.E.N." sounds so cool lol.
I took some time to understand the gameplay. I think the randomness of dealing cards can be removed in the 1st level , to make it more "tutorial".(something like giving same 3 cards in a turn until the right move is performed). If there are only 3 kinds of cards, the shuffling feels somehow meaningless.
I think it is a great ruleset for the battle part of a deck-building rouge-like game (SlaytheSpire-ish)! I like deck-building games so much.
