If you are a Whovian, you must check this out!
The game starts and feels exactly like a Doctor Who episode and then gradually transitions into a proper visual-novel experience! Even the dialogues feel as if they are straight out of an actual episode, which indicates the conscious efforts taken by the creators to keep the feel as 'Who-ish' as possible.
Short and sweet, the average play time is around 40-45 minutes (close to the duration of a DW episode).
