Idea: if you have any major characters(named, say like Puro(using him since he is dark latex that is named) as an example that they can keep prey longer/alive for more fun(an example of that would be the first pred you face on Press to Struggle)
I guess that could apply to mini bosses or main bosses , where the player is sorta toyed with for a while.
Follow up idea, mini bosses, and bosses, if beat, no longer kill player, if they nom them.
