You moved away from that door, making sure not too make a sound. You make a mental note that there is two possible people too avoid, inside this house, and move too find another room, still being as silent as possible now.
Excluding the kitchen, there are no other notable rooms on this floor. You decide to quietly walk upstairs to see what was up there, making sure no one heard you.
The next floor, if you can even call it that, is small, with only a couple of small rooms. To be fair, it seems like the heating on this floor works better then the floor below. You spot a laundry basket, but unfortunately, it's empty.
You can explore this floor, or continue upstairs to the top floor.
