I signed up, started the very first Delphi Pascal problem, and the test didn't run... it didn't crash, it just timed out.

The C hello world works just fine.

I've used Exercism for a number of years now and have enjoyed it. It's nice to see they added an editor in the browser so you don't have to use the command line to interact with their system. I'd like to see them implement vim keybindings for that editor (or maybe just embed neovim), and also offer a dark theme. I still prefer codewars.io because of the two things I listed, but I think this is a big improvement on their part.
