I'm not sure what to make next, can someone help me think of a game idea?

So I have been coding for about 4 - 4.5 years now and recently I started developing in Unity. I have already made one project (can download from my website, link at the bottom), but now I’m stuck I don’t know what to make. Can you guys help me come up with an idea?

I have also made a website with some of the other games I made in different engines: adam.edgenode.tech
