I do not see any place to submit runs if someone was to do an IL run for this game. I personally think that an IL section would fit this game, as you are able to select every level from an in-game menu. So why is there no IL section?

When I click "view all" on the level leaderboard, it shows some different times than the actual leaderboards do. Why?

I see some people have used emulators for their runs but the rules do not specify specific emulators. Is it fine to use any emulator?
