I've done 3 so far, and only one of the games I worked on was able to be played on web (it was a 2d game). Our team has found that getting a 3d game on the web is SUPER difficult because the moment you mess with env lighting, shaders, or anything that makes the game "pretty" does not work in browser. So I think having the download files is fine. Just for some reason chrome was very wary of yours and my only thought was because of what you called it. I'm an artist and not a programmer though, so maybe it has nothing to do with that. 🤷🏻♀️
