Invite a friend to either take control of the Owl or the Cat and find your way through the levels together.
OWL is a top down, rogue like bullet-hell where you go through randomized prebuild levels. Only when you are in beat you are able to defeat the enemies, as the enemies follow the same rule. So listen to the Music patterns your enemies make and predict their attacks to reach the final boss, Meowestro.
