In a run of Sworplay Showdown, are you allowed god mode?

Yes, if you look at the current WR, you see that I use god mode throughout the run. So to answer your question, yes, you’re allowed to use god mode.

ok, just checking. i have done runs that were invalidated because i didn't know something

It’s completely fine. I believe you can do runs do with and you can do runs without god mode.
