To claim any of the WRs you should post the level and time here. Then I can check the leaderboards specifically. If I happen to see a new one on the leaderboards I'll record it but it will help a lot if people can post when they beat a WR.
The oldest build (during development of original 1.00) the level had EE in a different spot, large IBT (for traps) and no gems. For 1.00 I added gems and lowered IBT and changed EE. I now reversed the level to the original.
