I really liked just skipping turns and seeing the units hectically shooting each other.
Gameplay was a tad confusing for me, I took a while to understand what could the cards actually do. Also, for some reason I thought I was the right side of the board. Took some turns for me to understand I was with the blue guys, but in hindsight I should have noticed earlier since the swap sides card has blue with a smile lol.
Sounds and music are top notch, very fitting.
Visually it is really pleasing, I would just like a way to actually understand what's going on from the get-go, but since this is a rather complex game maybe it would require some sort of tutorial which wouldn't be feasible in such a short timespan.
One really minor nitpick I got was the volume bar at the start screen made me uneasy, it seemed like it could move further due to the bar background. It was hard to accept it would only go so far considering the image.
Kudos on making such a well-thought entry!
