I liked the idea of a language with minimal syntax that is easy to learn and easy to understand because the code is forced to be straightforward. It didn't work out that way to me in practice.

It's a bit too low level for many use cases in my opinion, and that does get in the way somewhat. It also works against the "easy to learn" part unless you start with developers familiar with low level programming.

I also found some types of library code surprisingly difficult to read, especially when empty interfaces where used.

The standard library was great though, it covered stuff that others don't and it just worked out of the box.
