I am aware of this problem. I have now fixed it. Sorry for the trouble!
Nice! The game is very satisfying and intuitive to play. I find it amusing you can't step on the ducks, but you can push them off cliffs with no repercussions. Got a score of 300, beat it if you can
True, I found it best to do that so the player can choose between jumping over the ducks or pushing them off, which takes more time in some situations but is still better because it doesn't give any karma. Thanks for playing my game! :)
