I really enjoyed the loop in this game, I enjoyed battling through the early rounds only to come back and absolutely mow them down with more powerful cards and better stats. The only thing I would say is that the animations are too long for something you do repeatedly, particularly enemy animations and entering a level. Also, I was frustrated that you have to wait until the end of the next turn to reshuffle your deck, perhaps it would be better to reshuffle it on the same turn you finish your deck, so you don't have to spend a whole turn doing nothing. Besides these, I really enjoyed your game, I found it compelling and engaging, and I played it for quite a while, though I unfortunately could not win. Good work!
