The climbing and jumping animations are tied to the grid. But not the walking ones. This is not what happens in other games like Prince of Persia or Oddworld.

The climbing and jumping animations are tied to the grid. But not the walking ones. This is not what happens in other games like Prince of Persia or Oddworld. I agree that she is only in one tile at a time (her position is defined one position in the middle of both feet) But she doesn't just move by full tiles. You can perform step that are fractions of tiles, and combining that with the rotation angles (which are continuous), that must mean that you can be in any place of a specific tile (I.e, each square of the grid has infinite positions). Just tested it in TR1 demo, by rotating and walking backwards slowly, you can go to any place of the grid, and even have some feet in the air.
