I like the idea and its very technically impressive! I understand that it's a very early version, but would be good if the goal of what to do was clearer as the instructions appear for a short amount of time on the screen.
Cheers yeah I got about a week of work into the sim, but about 10 minutes before due date into the UX :P The github/netlify version will get updated as I progress, many stones left unturned :-)
