Blur sprite. Help please.

Hi, I'm making a MMX Game, but I see a little error (is not like very important, but still). When my Sprite moves and stops in a specific position, the image adds some kind of blur, you can see it here:

Is there a way to get off from this? Thanks

(Edit: Ignore the slope, I was proving the slopes behaviors hehe)

This happens when the game's sampling rate is set to "Linear". If a sprite occupies a decimal position, it will appear to be slightly blurred with "Linear" sampling. Go to the project settings and set the sampling mode under runtime properties to "Point". That should fix the problem.
