A user-created content piece for a popular sandbox video game, this falls under the category of downloadable additions that significantly alter gameplay. Players navigate a series of vertically-oriented levels, the objective being to fall through obstacles and reach a designated safe landing point at the bottom. Failure to avoid these obstacles results in starting the level again. This activity encourages spatial reasoning and quick reflexes.
The widespread availability of these downloadable additions provides a virtually endless stream of new experiences for players, extending the longevity and replayability of the base game. Their creation and sharing are vital to the community, fostering collaboration and creativity amongst players of varying skill levels. Historically, their popularity stems from a desire for challenges beyond the standard survival or creative modes offered by the base game.
