IGT is definitely pretty wack in this game but we should probably not remove it as there is not really any reason to and manually changing it would probably be too confusing for others looking at the leaderboards.
It may be a good idea to split that skip into a different section as i had not considered that wouldnt be possible in the original browser game, although I am not sure if this game is popular enough to deserve another leaderboard section
But I don't think that the 100% would be worth it, as there isnt a specific way to determine it, there is one side quest with the little monsters, but you have the choice to either grow or shrink them for different effects on the karma system, and I would not be sure if 100% would include interacting with all objects that effect karma.
