Music was fun and the art was cute. It definitely seemed like a fun concept, but getting dropped in I basically just got trampled XD It would have been nice to have any sort of reset or retry / "you died" / "game over" screen so I didn't have to restart the app each time. The other herds seemed to instantly all pop into existence so fast that I barely even had time to get my herd to follow me away from the chaos ^_^; (I also seemed to be able to leave the edge of the map just fine, unless that was water.)
Would be interested to see this mechanic in action if you do decide to work on it further! Great job! ^_^ Thanks for the game.
