Could it be that your disk is full?
If not you might have some luck clearing your browser cookies from narrow.one
My C: drive has 15.6 gigabytes available still.
Are you also having this problem when playing on https://narrow.one/ ? or only when playing on itch.io?
Maybe... I think that site is blocked for me though
I also cleared my cookies ;(
Well Jesper, I guess I won't be able to play narrow one in some time ;(. Thanks for the help...
