Feedback for my ExpressJS Template Engine

I created an NPM ExpressJS template engine called squirrelly (https://www.npmjs.com/package/squirrelly). I created it because I wanted it to be simple, it's really fast because it just uses RegExp to parse, and you can pass in options to inline JavaScript for advanced conditionals. Also, it's Express-compatible out-of-the-box. However, so far, I don't think anyone has downloaded it except mirrors. I would like to know what's wrong/what I could do better, but I haven't received feedback.

I don't know any other Node developers personally, and I would appreciate any feedback you could give.

Thanks so much!
