Changed screen dimension to match the one of the phone (800x480px).
Fixed error in plant model.
Created a platform with the same texture as the wall. Only did this for the smallest platform shape (which now is repeated to produce larger platforms). Re-scaled the wall texture to match the brick size of the platform texture. (I updated the UV map of the platform since the old one gave a strange result, thus there is also a new Blender file so it is easier to alternate the old and new platforms).
