your concept has big potential, if u make it just playable and find understandable, working and fun mechanics (not just invinsibility-reclock-mode). maybe add other time-mechanics like reverse-bubble that reverses only objects in the bubble area for a certain length. or reverse time with hero too, like in forza (could be a death-mechanic). maybe even OG slomo, why not. to make a game about time manipulations of all kinds.
