level leaderboards could be timed whit the in-game timer, as this more acuretly describes how long it took to compleat the level. For all spider you eather show that the scanner shows 0 at the end or the number of spider kill on the final screen is equal to the total number of spiders on said level. Full-game leaderboards should also have a set start point, for exampel the play button that open level select. some of the categories could also be renamed, as NG is not very usefull in categories other than NG+.
