Wow, I left this game wanting more! (In a good way). The presentation and the polish was some of the best I've seen and as a lover of card games this was a joy to play.
My only criticism stems from the desire to play more; At one point my strider was a 10/99 beast and I could steamroll through everything. A simple win screen, "You emerged from the storm" type deal around depth 20 would have been enough me for me to reset and happily keep playing. I would have loved to see a shop type mechanic, a wandering Bedouin trader in the desert I think could have really rounded this game out. At the moment I have no incentive to fight any extra enemies that are not blocking my path, these types of risk-reward decisions take the depth to another level in my opinion.
But Overall, what you achieved in one week was an outstanding Jam entry. I hope you go on to develop this more.
