I like the change in enemy size. It makes rats and puks seem more threatening. Also, I can see them in much more detail from the art department. Maybe they can be slightly adjusted, in terms of:

The bigger the dodo, the stronger it is (I.E. Roadrunner or Cockatrice) and the smaller, different colored ones are weaker.

That's the only change I would understandingly accept. Other than that, I enjoy all the mobs size increased, to be honest.
