I love procedurally generated levels in a way they make a game very replayable. Overall it was good and I also think it hilarious that the main was a duck but, there were some things that could be improved.
Small enemies like the bat were very difficult to get by and sometimes they just got stucked to you. Don´t get me wrong there is nothing bad about a hard enemy but one that is pretty much a run killer can be a bit frustrating the first time playing.
I managed to get to the green boss!
