I really liked your game, thank you!
The gameplay is fun, original, simple but very efficient!
The music is great, and I also loved how you used some storytelling to explain the "2 extra jokers".
In my experience, for any progression level, the map layout has a HUGE impact on difficulty. It's nice that maps are partially generated with some randomnes, but maybe this can make some levels really unsolvable, for example due to a canyon in the middle of the map, splitting your troops. That's a bit frustrating sometimes, but I really like the game overall!
