It's really cool conceptually with the cast of characters, and the voice acting is good, but none of the characters feels particularly satisfying to play.
The only character that has any impact is the turtle, but the downside of the character make him sluggish despite the balance justification.
Wherever you got the models from (not sure where any of the animations, models, sounds, music, etc came from since I didn't see a credits section) are slightly random and don't make for a cohesive visual style. The rigging of the animation on the models had some clipping and texture stretching too.
It would be good to have the ability to skip the voice acting on replay, and the UI isn't immediately obvious in what it represents.
With some work though this could be something really cool, keep at it!
