I think some of the cards in this version might be bugged, honestly trying a few out I can't tell if they are or just not great cards. lol after playing for a day I put together a deck that ramps up growth thanks to Trading Post's specific function of removing and adding.
I think the biggest thing the game needs is some sort of wiki or something to look up all the abilities at least if not all the cards. There's a bunch of cards I have no idea because I got bored with trying to make a deck just to try out the handful of cards and trying to get it small enough to actually see it but large enough to not just die.
Related to that, does the demo version only have 3 levels for player character art? (v8.6) I got up to like 4k day 1 with a legit straight up roulette win (I then later tried save scumming to peek at more cards :p) and got a new art, but now at 90k it's still the same.
