When we equips Invisibility Cloak, please allow game to display our pony at least unclearly (e.g. a highly-transparent hollow pony or an outline), do not just completely hide the pony even to us players.
What I mean is that we need at least an unclear sprite which limits our ponies' visibility but we can still find our ponies if we look carefully. Currently, Invisibility Cloak provide invisibility not only to enemies' eyes a but also to us players'. We cannot even know how to move if we are totally unable to see ourselves. Even invisible ponies don't be completely invisible.
