Is this run ends after 40lvl reach? Coz there is 55 levels

I think after 1 year i can repeat this question: "Is this run ends after 40lvl reach? Coz there is 55 levels"

Rules say it ends at the last boss which is lv.40. But it doesn't matter since nobody bothers playing 40 levels in a row.

Seguro gionni? Eso lo veremos
