This is wonderful game, I play it way too much than I should :D You did a good job.
I know time constraints limited you and you going to improve game later, but still would like to say some things I'd like to see in it:
1) Preview of figure action. Machine Gun should show 3 squares it's gonna shoot, artillery show where cross area of explosion will land, Naval Bomber explosion radius and so on. As an addition, maybe this should include pincer attack preview, so it would be easier to see that some figures don't have this attack, like Fortress.
2) Visual representation of armor on top of figure, especially when this armor gained throught Fortress. They could be represented with little blue shields somewhere on figure. Currently there is no way to see it, but remember when figure got a shield.
3) Bot (Satori) actions should have some delay, currently she places her figure immediately, which sometime makes game look chaotic and difficult to comperhend.
4) Probably difficulty should not be named that, but instead different games or gamemodes, as they change rules compared to Hard difficulty.
5) RNG should be toned down, sometime it's way too unfair. I had a game where Satori got 3 LG almost in a row. Meanwhile player's chances of getting LG is extremely low, up to making me believe it's Satori only figure, untill I got it once. I hope you will sort everything out by time you will add multiplayer.
6) Meanwhile it would be great if you add hot-seat multiplayer on one PC, that should not require a lot of work with networking, people craving for any kind of multiplayer right now.
I am looking forward to what you will make this game into, good luck
