My Express Template Engine: Feedback

Hi! I have been working on developing a Express Template Engine. I was pretty confused by some of the other alternatives, so I decided to create my own. I was hoping for some people to use it, and to get some help with contributing. However, it hasn’t taken off at all; what should I do better? Is it just a crowded field?

My Github Repo
My NPM Package

Thanks for any advice you can give!
