Ratings and reviews

The puzzles are fine and it teaches you reasonably well, HOWEVER: 1. The actual text input field is extremely annoying, in that it will almost always select text instead of letting you insert a character. This is frustrating for obvious reasons. 2. A lot of times it feels like there are more matches being done in the background to verify your input against some other unknown criteria, resulting in only specific solutions actually counting as valid. It's unclear why other solutions are 'wrong'.

not got far in but so far it seems very clean and easy to understand. if my thoughts change i will update this post but so far a fun way to learn. would be nice to have quick buttons above keyboard fir symbols not common on keyboards because I have 2 press like 3 buttons to get to the right page for some of the symbols such as "|"

Was ok but goals became unclear after the "intermediate" section. Explanations became unclear after the "advanced" section. Goals for each exercise need to be clearer about what they ask asking for and lesson explainations need to do a better job of explaining what is going on. For example the goal was "Ensure that once a repeating "a" sequence is matched, no backtracking occurs." "(?>a+)" is what I entered but they expected "(?>a+)b". Nowhere was the "b" character ever mentioned.
