10 days :o impressive! you did all the art, programming, design and audio? or you had some asset banks?
3D Art and sound is all marketplace assets just slammed together (except for the faces of the characters which are just basic spheres with textures painted on top by my friend who did the whole UI). No way I would make it in time otherwise. The characters are made of at least 4 different asset packs so they look original at least.
All logic and design is made from scratch.
