Add a category for fastest time on the Peking Express achievement.

no

Sounds good on paper, but when you think about it, it's not something challenging to ran. I did my own category that is also an achievement; that is Last Mower Standing.

A leaderboard for that already exists automatically on mobile iirc.

Where can I see it again lol

I mean like, some of the categories like Vasebreaker Endless; time ends when you reached 15th Wave, just like the achievement.

perhaps time it takes to beat each world? (if so, maybe on adventure I mode instead of adventure II)
