An unusual, but surprisingly fun combination! Panically shuffling card signs while dodging enemies until the ability to retaliate felt like a great loop. Would love to see the two more... joined together? I kept looking away from the arena oh gosh I'm playing candy crush while driving.
Found that I was getting too much energy and too few cards, though. Matching 5 helped but still felt tedious.
Regardless, I still enjoyed it. Would love to see it more fleshed out and with more content!
Also trying to match when the timer was going made it bug out, might wanna look into that.
