Hello, Im glad to hear that you are impressed with my game. For audio, animation and player movement I used 3D Game Kit as I say in description of the game. Level Design and art I did on my own and I used assets from AssetStore to create art and level design(there are 2 levels). Its not very hard to make a 3D game with 3D GameKit. Try on your own. As I say Im glad to hear that you love my game. That gives me more motivation to create more games. Thanks.
