Thanks for giving my game a try, and glad you enjoyed it as far as you got! The two things you need to know for "Push Pals Unite" are that you can change your friends' directions, and that every friend gives you +1 pushing power.
As for the aggressive elephant, I sort of combined the idea of a literal elephant in the room with the metaphorical version, i.e. it's something you and your friends don't want to acknowledge. So acknowledging it had to be a bad thing!
