Beautiful art and smooth gameplay that's fairly intuitive after a short period of getting familiar with it. Had a crash when I tried to restart the run mid-fight, but other than that only encountered some oddities (like one enemy after the first boss only ever summoned one minion, never attacked and otherwise kept healing itself, making it kind of a pushover). The "Resistance" stat was confusing at first before figuring out it's basically just the HP of the card.
Card crafting mechanic seems interesting, seemed fairly balanced at first glance though not sure how broken it could be with more experience with the game. At the moment class and stat balance seems a little odd to me: Wizard's special ability seems fairly worse compared to Warrior's for example. as skipping fights not only skips the actual gameplay but prevents you from getting rewards as well, which I'd imagine could bite you in the long run. (Maybe something like allowing you to escape mid-fight as would be more useful?)
Stats are an interesting twist, but having only one stat directly affecting combat makes it better than the rest in my opinion. Intelligence might give you more options for card crafting for example, but you're still limited by the resources you have from what I understand. For Dex, getting first turn is nice but is it worth over more HP? And while Luck seems interesting and some items do seem really good (vampiric vest or what it was called carried my first run), direct survivability still seems a better option in my eyes.
I guess my point is it would be interesting if every stat affected the direct gameplay in some way, which would give you different builds for fights on top of the deck builds you can get.
Regardless, still a solid entry to the deckbuilding roguelike and I'm interested to see how it'll progress.
