Pretty cool! It'd be nice if the salaries were always displayed on a static HUD so it's easier to adjust and compare wages on the fly, but it worked alright as it was. It was pretty fun to finally get your knights moving on the offensive, only to have the enemies launch an attack and be powerless to call them back.
I felt like I was cheating a bit towards the end, I started using flags as a decoy to lure enemy units away from my base. But then I had a thought! I actually had more control over the enemy units than I did my own! An RTS where I only have direct control over enemy units? Add a cost to planting a flag, and that could be a legitimate mechanic!
I had fun, it was weirdly satisfying watching the enemy hordes tear down my little town.
