"Phone in Mouth" is a short story about a journalist discovering the subculture of "oralphones", people who put their smartphones into their mouths. As the term "short story" indicates it's not a game. The writing isn't remarkably bad, but "interactive" means more than occasionally pressing a "continue" button.
The game comes with several comfort features and may very well get interesting some time into the story, but hilarious parser problems prevent initial progress.
Lost and Found plays in modern day Tokyo, but not in the glitzy entertainment districts, but in the unhurried suburbs. The player is a homeless tutor who lives in a park near a school and encounters a female teacher who leaves an enduring footprint in his life.
The setting is fresh and well fleshed out. As a game, Lost and Found sucks as it's just a gamebook with merely a handfull of choices to make. But the writing is good, the story is good, the pacing is good, and so it's a good read. Done in 15 minutes, but it's exciting and emotionally affecting. Recommended for people who love fresh settings and who don't expect a game to be an actual game.
