First, Thanks for Playing. and review.
You are a curious and smart soul, That means you are my kinda guy :D
And because CODE is an hidden world, It's feels awesome when you successfully guessed what an app is doing on that side.
That's the reason i want to give you another chance,
Shadow Check : Think about a correct rotation, and then rotate it at Unity's Z angle, all values between 0-360 are correct values and gives a correct looking shadow , and we haven't even flipped the object yet. So Quaternion or eular angles will give you infinite possible answer.
Elephant : People mostly focus on teeth, and often forget to look on ears that has to be smooth as well.
BTN : Most of the team member quit before we begin :( So we two didn't want to touch that button.
