[IOS][2010-2014] neon ghost or something ceating bubbles

I vaguely remember playing this on the i pad of my dad back in like 2012 or something.

You where maybe a neon ghost or arrow, and you had to defend yourself against turrets and other enemys.

You could delete them by swirling around the enemy to create a bubble.

It was just a black backround or maybe black with a neon grid.
