Hey people. I have a question about this rule.

It says in the rules: "You must not retcon the wildly unpopular twist. There are No Giant Robots in the Steel Love universe."

Does this mean the only thing we cannot retcon is "there are no giant robots in the steel love universe"? For example, do Singuliera and Averagmus/Gigantimus have to stay split up?  (This isn't my plan) But if they were to say, get back together under a deal that Averagmus would wear the giant suit sometimes, would this count as a retcon? 

I don't believe it would count as a retcon if they got back together as long as what happened isn't forgotten.  They could reconcile, but also I'm never going to believe their love will ever be the same as it was 

I've already made my mind up, but mecha is fair game right? Aka giant robots that are just vehicles. Just no sentient giant robots and that any giant robot all along were actually mechs.
