Hey, really nice start from my point of view.
I have a little question : have you considered to fill the shapes on the second pass ? I believe they will be a lisibility problem when the shapes are charging in term of Gameplay.
The attacker, as the marked, has to know very quick if the mark is completed or not. I guess it’s better thought on the second additionnal iteration because the shape is different when the mark is filled.
Take a look on how Riot deal with this on League, and think about the gameplay behind : is it something about to deal damage when the mark is filled ? Is it supposed to snare / root / stun the target at when the effect is filled ? The indicators are differents depending of what will append to the target !
I know it’s a creative challenge searching from fresh idea, but I guess it’s a good way to look what already exist in order to achieve a good comprehensive effect !
I am very open to discuss this with you
However, I will looking forward this effect and look watchfuly your next iterations ! Keep going bro
