My Take
I would highly recommend this series of lessons especially since it's a fun way for kids to practice the topics we've discussed in our digital citizenship lessons.
I think the level about secure passwords moves pretty slowly for kids who would be able to handle controls as the character glides through the valley. A way for kids to adjust the character's speed on this level would be nice. It took so long the kids start losing interest.
I tested it on a Chromebook and was glad to see it worked. On my lab computers (MacBook Airs) the fans started kicking in after processing the graphics.
How I Use It
I teach lessons based on our CODE.org/Common Sense Media lessons and then I give kids a link to a level of the game that pertains to the lesson. Kids enjoy it and it reinforces the lesson.
