Thank you for you feedback. I actually started a little late and in general made a 3D game for the first time with aim of publishing, I am also new to the game engine and was learning stuff as I made the game. I was planning of making music and sfx but in reality not very good with it. I kept art work minimal as I was planning for a webgl game and feared if it could handle heavy visuals and in fact there were some bugs with the loading times with the game with even these minimal graphics. And I wanted to learn all the aspects of game development like art and music so I was avoiding using pre-made assets. Once again thank you for feedback and I will try and improve in the mentioned fields.
