Nihilumbra is a classic platform game developed by BeautiFun Games in 2012, initially released for iOS. The game is now available for Windows and offers an innovative twist on the classic platform genre. The protagonist, Born, is a black creature that navigates through five different worlds, each with its unique setting. Born's goal is to escape absolute emptiness and reach a new life. However, this isn't easy, as multiple enemies block the way and can't be defeated.

The game's key feature is the ability to color surroundings. The player gains a new color in each level, which can modify the setting. The blue color makes surfaces slippery, while the green color allows Born to bounce. The brown color slows down characters walking on it, and the red color burns monsters. Finally, the yellow color conducts electricity, and Born must use it to solve puzzles. The graphics are set in dark colors, and monsters are the same color as Born, black, and each of them is deadly. The sound effects are quiet and support the game's atmosphere.
