Targeting needs adjusting. I wish I could adjust how a weapon targets a unit. Sometimes, it's better to have the target be the closest to the destination. Sometimes, it's better to target the biggest unit. But the player should have that choice.
While I like the game, the interface is awful. You need to find an alternate to scroll in the game other than "mini-map." Also, I think accessing staff and stores to upgrade while the game is paused is a necessity.
