There's a lot of good, but the devs def screwed up with the whole shared breathing / eating tubing. But at least the playing ground is partially even, with other species also at risk of randomly dying from the simple act of food intake.
The most screwed up one is the octopus, for some reason that brains are below their mouths so the esophagus goes through their brain. If they eat something too big they can give themselves a concussion.
