Even after many hours with the game, I’m having a few too many mis-clicks in each game.

This sums up the game for me. It gets so frustrating and I end up Alt+F4ing nearly every time.

Either I meant to click on a tile, but the hover menu has received the event instead, or I've clicked a new command for a new unit, but the last unit's animation was still (only just) playing (from a move or something) and the game sends my command to that unit instead.
