My item keep getting rejection.

Hi, I create HTML5 games and publish them to codecanyon. Everything was going fine but this month when I try to upload my new game codecanyon keep rejecting my item even though I included every documentation file … source code… assets etc as I did in my older projects. It says “unfortunately we found it isn’t at the quality standard required to move forward, and you won’t be able to re-submit this item again.”. What should I do now??

Find a better idea or improve the design/coding
