A Newbie Trying To Use Google Adsense And Get Approved

Hi there! I am a high schooler and made a small video game for fun and to improve my skills. However, I thought it would be even cooler to try and make it into actual revenue. I used weebly to make a site that was deployable, and applied for google adsense. I got rejected and suspect that I do not have enough content to justify adsense. I have asked questions before on their forums, but I never get a response back, so I wanted to ask here. What is my best course of action to get my site approved for adsense? Any help is greatly appreciated, and please let me know if anything is needed!
