Thank you very much for playing the game even if it's not your type.
The game really needs a in-game tutorial, at the moment there are full instructions in the game page, if you want to know how it works and what it is not really functioning, due to the time limitations of the jam. That could be the reason why it took you a bit of time to create the deck.
If you are curious to see how the game will evolve, follow the project. I'm willing to continue to develop it and involve the community for the creation of new cards.
