Fun: Juggling with the bodies and balancing between eating or breaking them feels really good. It was a bit clumsy at first, but I got used to it quite fast. Grabbing the bodies requires a lot of precision and feels quite annoying at times (maybe its a good idea to increase the grab area size). Also, missing an enemy creates a strong negative feedback loop (as the enemies start to pile up and kill you very fast), I think it would be better if enemies died after attacking you (e.g. eaten)
Originality: The swinging/juggling mechanic is not new in itself, but with pushing objects around it feels fresh and original
Presentation: Crisp sounds and blood splashes add a lot to the immersion, also dynamic lights are a nice touch (might have looked even better with pixel normal maps)
