yes the map loops into itself , now the game opens up a lot , there are a many secrets and new abilities hidden , just try exploring the old areas and memorize the map layout .
I know that this part is very slow paced , but that's a design choice i intended , if you played hollow knight for instance , this would be the part after the city of tears , where the game lets you explore almost the whole map , it is the feeling of being lost in a unknown place and slowly figuring out where things are , its that part of a metroidvania I tried to replicate , it is my first one tho , so if you really cant find anything at all I will give you a hint .
but maybe this is just me and the being lost part is not enjoyable for most people and I'm just weird ..
