i dont know but Web Versons of game run varry diffently as site like to save props and sometimes run diffentlly so idk
edit: i just played the Web Verson and found out some of the levels are Changed or Removed completly so a diffent catagory will probly be needed
the web version has fewer levels, but as far as I can tell, the levels that are there are identical. except for level 19, which originally was the same in both versions when I first played the steam version, but then the barrels on the narrow paths in the later part of the level were removed.
so a separate full-game category would make sense, but for the individual level leaderboards, I'd only split up level 19. unless I see a clear difference between the web and steam versions, I don't think it's worth the effort to treat them differently. they're most likely both exported from the same unity project, so they should probably work pretty much the same.
I played through the web version now, and noticed that it doesn't show a leaderboard like the Steam version, so I modified the IL timing rules to time between the text popups, which works for both versions. I didn't want to start time from first input, because then a player could wait and not press anything while the level is already running.
