One thing this game really needs is something that indicates when the player can move the tiles and use the heroes abilities.
It could be a simple thing like putting a transparent white overlay onto the hero cards. When it’s on you can just sit back and know it’s not your turn - instead of madly jamming at your charged up healer hoping to be allowed to juice up your team before the opponent launches an attack that suspiciously is just exactly what’s needed to take out your healer. No more scratching and scrabbling at the tiles when oh, hold up, the opponent has one more go at you before it’s your turn.
This would be extremely helpful fighting titans.
