DoctorTale is a crossover fan-game based on the sci-fi series Doctor Who (by BBC) and the RPG game UnderTale (by Toby Fox).

The plot tells of the Time Lord from Gallifrey, traveling across different planets that are imprisoned in one large Pocket Universe which is on the verge of self-destruction. In this world, you can go the way of mercy to save everyone, or you can use brute force to achieve personal freedom. You decide, the fate of the universe is in your hands.
