We've added a Time Trial Leaderboard for each individual level.

I personally want to apologize for how long it took for this to be added. When the game first released we planned on having a separate website developed that could better realize the capabilities we wanted out of a TT board. Five months in, and there has been no major progress made on this site, so for the time being it makes sense to just host the Time Trial Boards here instead.

Enjoy!
