Well, it's certainly up to you guys what you like to document and such so don't worry too much what I think!
Although if you want my personal opinion, I consider only TPOF and the information on my website [ dirtymurdergames.com ] to be 'current canon'.
Anything that I posted on my old social media and whatnot is subject to change for my newer games [ or was never said seriously in the first place, it was just social media posting after all ]
Lots of stuff in the old BTD games will be changed to fit my narratives better in YKMET as well. I know 'retcon' isn't the most popular thing but my personal motto is that 'improvement is better than consistency' haha!
