I had a lot of fun with this, there are a lot of well implemented ideas.
The cards having different attack powers and some of them aiming at enemies is a really nice touch. Sadly, since the luck meter decreased pretty quickly, I ended up mostly spamming and not really caring about which cards I had.
The concept of collecting luck to have better dice rolls is something I surprisingly hadn't really seen before, but definitely fits the theme! It's a great way to give the player a little more control over the complete randomness of dice rolls.
All in all a great game with lots of interesting concepts! Great job!
