Bats have extremely low HP and low damage, but could be a distraction since they are aerial and very fast enemies. Bats could be found by smashing jars. Bats coming from there have the same level as yours so they could be a bit hard.
Usually, bats attack from charging from the above. It is possible to attack them on the ground by jumping or by using the tiger jump.
Tiger jump could be extremely helpful here since they give you time to attack them.
