Erectoplasm's manga / #another world(2)

Read a long while ago but iirc a bunch of humans get transported into this death game like world except the mc gets stuck in a level after almost dying and becomes OP

Started off strong but I feel like it got really weak near end after she abandons the duke so I dropped, but before that it was a pretty cute slice of life of a isekai’d maid looking after a cursed child who was thrown away by his parents and treated like trash by everyone
