I'd say it shares a lot of similarities given that both languages look indented and have similar keywords. The main differences are going to be the tooling, the portability, and the syntax itself where Loreline tries to avoid the use of symbols, favoring the semantic structure of the script instead and taking advantage of the indentation.
Choice script is a terrible proprietary language-- I dont recommend anyone use it. Ink or Twine are much better tools. While Ink is built by a company the actual tool is free and open source
