I need a Blender pro to help me with animation...

[The chaser]

So, I'm making this custom monster as a test, and I was making the "walk" animation. The thing is:

To make a walk animation, you need to move the character and the legs, so you can see how it looks (and to have a clue of how it moves).

The thing is, I need to delete the Y location keyframes to make it good for Amnesia, but the animation still moves in the Y location after I delete the keyframes... any clues?

I'll give models and provide more information if necessary :$
