I use machine translation, so some of these places can be a little weird. I think the current version of the leaderboard is very necessary to change.Obviously, floor 0 is very different from floor 10.In this case, if it is purely for the sake of ranking, then we naturally will not choose a higher difficulty. Now not only is there no distinction between mg and nmg, but also difficulty.In my opinion, Joan Skip and One Punch Man Bug should be classified as mg. In fact, I scored 14min in the low difficulty in just an hour last night.It is very easy to exceed the current world record without using the above two bugs.I can contribute, but this will overwrite my original record of 15min31s closing the highest difficulty.I want to keep it, which is the second reason I want to change the leaderboard. There are already many players who have expressed their dissatisfaction with the current leaderboard rules.Now that the floor has been divided into four grades, it should be allowed to have some practical effect.If possible, I hope the community will further judge the Joan Skip and One Punch Man bugs.Even if you do not distinguish between mg and nmg, you should distinguish between difficulty.
