I generally adore speedrun-focused games. Bound is one such game, and is additionally really unique in its artstyle and presentation.

Despite being in 3D, Bound doesn't require too much precision and thus still feels great to play and sequence-break, although there are still a few moments where the camera can be your worst enemy.

Also, the 100% speedrun can be a pain, as some of the collectibles blend with the background and can easily be missed.
