I love the interface. Very thoughtfully done. They only thing it's missing is some HUD feedback about the currently active minions. Right now I can't tell from the HUD how many minions I have, what kinds, and what their health is. I know I can select minion types with hotkeys, but it'd be great to be able to interact with them via HUD icons too.
It's just difficult to look at the gamescreen and find/count/evaluate health of all of them.
Even just a little number next to the Idol Icons showing whether both, one, or none of my minotuars are still alive would be fine.
And maybe another icon for specials.
That's all. It would improve my life tremendously.
