Pretty silly but ultimately fun story :D the chickens weren't much of a threat, except for that congaline that showed up when you jumped down a cliff in one of the later levels :') and I liked that there was a boss at the end.
I sometimes had trouble shooting, not sure if there's a trick to it but sometimes it just wouldn't fire even though it should as it was way past its cooldown. But then it was fine a few moments later.
Overall it was enjoyable to play through, good job :D
