I noticed this as well the other week when I picked the game up for a bit again but I hadn't had time to bring it up yet. I'm not sure if there's any way around it at the moment, so if we find that it's just a hard timeloss that has to be taken from playing on the current version then it may be worth going back and marking runs with their version numbers at least to differentiate. I'll bring this up in the community Discord as well, thanks for pointing it out.

We can definitely look at adding those - they'd probably go under the "Levels" tab, and we'd have a new "Races" category to house them. We'll talk a bit in the community Discord to see how people feel about rules re: different platforms/video evidence/etc.

I've added a guide for those looking for information on that here! All you need to use it is LiveSplit and a set of splits for this game.

Sorry for the incredibly late response, particularly with the new SRC layout it's kind of hard to remember that threads exist. Perhaps you've been there already under another name, but the #sr-discussion channel in the Tinykin Discord server is probably the quickest place to get questions answered :)
