The reason you are getting the jagged lines is because you have shrunk your animation down from within Construct 2 to a size of 41.25x107.327 from 195x396. Shrinking objects can reintroduce jaggies (or whatever the industry term is).
Try placing another instance of your player_Image sprite somewhere, but keep it at its full 165x396 size. You should notice the lines are smooth.
I tried playing around to see if keeping the dimensions as integers or keeping the ratio of the dimensions the same helped, but it didn't seem to.
I would resize your animations within blender and redo the antialiasing there, then reimport them into construct without changing the size within the program.
