For some reason the Originality Art and Sound did not match to what I answered in the submission form (I even tried to edit my submission form): So I'll answer it here, MAJORITY of all the art (models and pictures) and sounds (music and effects) were made by other people outside of my team. (This is due to the fact of me not reading and understanding the rules carefully). However I credited the artists and composers accordingly in the credits section in the game. I invested too much in my project to do a major overhaul when I finally understood that making our own art modes and pictures is highly recommended.
Another Note: The unity version I build the project upon on Unity 2020.10f has a buggy WebGL build, so I really have no choice but to submit a PC .exe build :(
