You've got an interesting start to a game here! I'd really like to see where you take it. I was extremely happy to see you'd included WASD as a control schema, felt a lot more natural to me than a lot of games in this jam tonight (for some reason, most only did arrow keys, which my keyboard barely even has!)
I think a sort of tutorial level would be extremely useful, and maybe a count-down or turn-timer equivalent that lets you know when you're about to end a turn. The text for the buttons and the buttons themselves were a bit small, not sure what you had your scale settings set at, but it largely worked, was just somewhat hard to see.
You did a pretty good job, considering you haven't submitted many games to the jam before, so well-done!
