What happened to the category for nightmare mode (On/Off)?

In the current version (6.0) new characters were included. I played in Arcade mode and the inclusion of these characters doubles the speedrun time! Therefore, at least in Arcade mode, the inclusion of the variable for this version is necessary.

Please update!

I realized when sending my run that the Brazilian Portuguese language is not available, however it exists in the game! Can any admin include this option?

Thanks. =)
