what a great game! I really like the ideas, idk if it fits the theme well fully? just cause while yes I do have one, i can always go back to it, but thats just me. I also wish there was a way to fully see the level, that'd be nice! I know I can preview but i tried everything and couldn't move around?
One last issue is sometime my guy just- moves into death? I assume this is when you have no moves at all but I thought it was a bug, I think it should be communicated more if the player has no moves left (if this is the case for it) like maybe the guy dies and loses his flames, or shivers and turns icy, just another way to directly tell the player "hey you ran out of moves, try the shop again!"
otherwise I really like the idea, concept, the fact you choose which cards, can can preview the level (somewhat) and the art is sick! I really hope your team expands on this, i'd love a full game of this with more cards, levels, even characters and body modes!
overall great work!
