One of my all-time favorite games. Nihilumbra is a side-scrolling puzzle game, where you control the lone protoganist, Born, guiding him through five varied realms. Born is alone, too- aside from the enemies in the game, which are few and far between, every landscape you travel through seems abandoned, deserted. It adds an apocalyptic feel to an already stark and melancholy game.
Born starts out with very few tricks up his sleeve- he can jump and move inexorably to the right, and the enemies he encounters are deadly. As you progress, though, you pick up new skills that allow you to alter the landscape around you- colors you can paint on the world to allow you to slide, bounce, stick, and more.
There's really two parts to this game- the story mode, which is relatively straight-forward but still retains a challenge, and the mode you unlock after beating the story, which is devilishly hard. The controls seemed fluid to me, though they take some getting used to- one hand moves Born, while the mouse uses the various colors to guide him along. The game rarely rushes you, and when it does, it's considerate enough to provide enough checkpoints to prevent too much repetition.
This seems to be Beautifun's Freshman game for the PC, and I am definitely looking forward to where they'll go from here.
