After clipping into the backrooms it took me 2 days to advance to the 2cnd level, here I will recounting my experiences on level 0 of the backrooms
I wandered around for awhile until I realised how big of a space I was in, I had heard a couple of things about this place so I had some information on my belt. After awhile I found a corpse with a cartoony smile indented into it's head.
The body had some supplies including a bottle of almond water and a plastic bag with grinded up concrete and plaster labeled 'food' ,I collected them because it was better to have that than nothing, that's everything significant that happened while I was on the ground level, I could tell you this because of the decent internet connection on level 1.
