All categories on the level leaderboard that were either based on getting the highest score or based on getting to an arbitrary score the fastest have been removed. This is partially due to their generally uncompetitive/speedrun-like nature and also the overall lack of runs on the board. The categories that remain are Cruise Controls and the three normal levels of Sneaky Gamer, as those have a set endpoint and can have timesave/timeloss.

If you want to submit scores for this game, there are sites dedicated to that, including Cyberscore (although there may be other options as well).
