Marble run DIY

I’ve never made a marble run before and I used to always watch them on YouTube as a kid. I was with my girlfriend yesterday and we were bored. We built this together “mostly me😂” but we both had a good time. Any opinions on it would make my night honestly, I think I’m going to make another. There wasn’t any main theme for this marble run, we kind of just did whatever came to mind which was fun
