Yeah I understand what you mean by the flash having a cooldown, but I'm not sure if the "doll get away from me" effect part is following the cooldown too? I noticed that the dolls/mannequins would sort of twitch in their starting spots if I pressed space again even if the flash was cooling down still, which to me seemed like maybe it was moving the dolls back every time I hit space rather than every time the flash actually went off? I could be wrong about that though, it's just something I noticed since I was hitting space repeatedly a lot haha.
But that's just a nitpicky thing, all in all, still great work!
