Hi! thank you so much for your feedback!
about the leaderboard, sadly there seems to be an issue with the entries, as you said, sorry that you lost your good run! :( BUT I believe the issue is fixed if you reload the entire page, at least for me I then was able to update my entry! and also, yea, there are some shortcuts to take for speedrunning in the later loops. ;)
Aaand: congrats on getting the secret skin! we believe not many figured that out lol.
