UFO 50 is a collection of games developed by Mossmouth for PC released in 2024. As the title implies, it features 50 different games across several different genres, ranging from platforming, strategy, fighting, shoot-em-up, and more.

This particular TAS plays Mortol II, a platforming game and the sequel to Mortol, where the Mortolians need to infiltrate and destroy Castle Nilpis using a limited number of lives (99, to be more precise). The whole game is set on a single large map, encouraging exploration.

Fuirya however, immediately sets to destroy Castle Nilpis as quickly as possible by getting the minimum amount of keys required to access and destroy it.
