Wow, that's a great use of the card limitation. The game feels very polished overall, too. I feel the cards you get are a bit too random , but you can still play quite strategically so that's not really an issue.
Considering you used Godot, I'd have loved to see a Linux export provided so I don't have to play the game through Wine. So far, I was able to export everything I created in Godot to Linux without having to reconfigure anything, so it shouldn't require any additional effort.
Wonderful game, good job
