Doctor Who: Lost in Time is an official, idle game from Eastside Games and Bigfoot Gaming, using licensed characters from the BBC TV series Doctor Who. It had an initial release in June 2022 and a full release in March 2023. I played from March 2023 until December 2023. Aside from occasionally ignoring the game for a few days, I checked it almost daily.
Theoretically, idle games allow casual play, with players accumulating power while away from the app. However, in practice, this game is frustrating and requires a lot of dexterity, effort, and a major time commitment.
