I've decided to keep the game's leaderboards to IL's only until it is announced that no more levels will be added to the base game. You're welcome to post your full game runs in the forums if you wish, but a leaderboard is hard to do with new levels being added.

how about different leaderboards for every pack of levels

I think with the 1.0 version being fully released, the legacy version shouldn't be getting any more new maps from now on.
