Someone mentioned nim on IRC. I looked for some games written in the language. I found SmallTrek. It can be found on itch.io. That includes a link to a web version. I've really enjoyed trying out the web version.
Unfortunately I have not compiled it locally. Nim on Fedora is verion 1.0. It needs 1.2. Tried taking the 1.0 spec and substituting the 1.2 code but some tests fail.
