Helo there!
It does have Iddle animations. Iddle and attack animations have 2 frames each. The first two frames from each row in the entities files are the frames for the iddle animation, wich is basically the character going up and down.
See the left half of the fourth image from the assets page:

Hope I was able to clear things. Have a nice one!!
