Goes through the first movie in the game, Raiders of the Lost Ark.
Saved about 40 frames in the first 2 levels from picking up the whip in level 1 and better rolling.
Couldn't find any other uses for the floor clip, other than the one in the penultimate level in movie 1, the level before it looks like it should have some useful floor clip, but in every ledge where it can be done there's extra collision inside the floor.
