Escape Game Dog's House

Ads are hints, answers only! My reaction when I saw the hint from an ad for a problem I completely couldn't figure out! 'Oh, so that's it!' I missed it! It was a fun game with cute graphics! ↑What I left behind as the vanguard A felt-like dog and a cute, rounded single house. I thought Dog's House = doghouse? but I played it thinking of it as a room with a dog. This is also the type where you go back and forth between rooms.
