Yes, but you must use separate layers that act like frames. Remember that a decent frame rate is 24 frames per second...or 30, depending on what you want.
The bottom of the layer panel would be the first frame, and then you just add a new layer and re-draw the stick figure(s). You can play it back by going to View>Playback Animation (I think that's it). Then you can save it as a .gif image. Unfortunately there's no support for saving a direct movie file (like .AVI or.MOV), but if you save each frame individually to a dedicated folder on your system and then 'build' the footage in a video editing app, you can then save a movie file.
Hope that helped.
