Every thing was made and coded by me including the lava and other materials, and the custom models. 
From what I saw the project looks like finished.
Can you be more specific … What is missing and what is not completed?
Maybe I can connect you with people that are able to help you.
There are a lot of things missing, a leader board, a proper score system, a store to buy in game items like new players and upgrades, a local multi player system (I had made it but I scrapped it) and more, it is far from finished!
