Thanks, this is really useful. Showing the wrong colour once and then the right one is a much better teacher than a help panel, so we’re going to try that on the first level. Good point about phones in sunlight too: we’ll give the matching walls a pattern, not just a colour, and give K a small breathing idle so standing still doesn’t look frozen. If you get a run in later, the LN3- code and a line on where you stopped would help us a lot.
