“Once Upon A Timeline” by Adam Findlay, Kevin Carthew, Oli Wood & James Ferguson.
“Your aunt Jocelyn is a brilliant scientist and inventor. You and her are close, and she always replies to your letters. One day the replies stop. Fearing the worst, you arrive at her home to find her dead. What caused this, and […] what is that strange looking machine in the corner of the room?”
The design of the time travel puzzles in “Once Upon A Timeline” is well done. To solve and prevent the murder, you have to travel through about one hundred and fifty years. Each time a small detail is changed, but this can have a great consequence. [PLAY]
