Hi Luca, thanks for introducing the game! If I remember it right, the game has been in one of our in-class examples and I finally have the chance to play it. It's cool that even I as a master's student cannot hit the target every time, pointing out we still have some blind spots in this topic. Also, if you didn't point out I may stop in the first level and won't know they have a new game mechanism after the second level! In terms of the suitability of the game for kids, I feel like it could still help them to learn the idea through this exploring process without explaining anything. But as you said there are still other ways that could introduce the concepts in a more instructional way, which could help players learn the concept more structurally.
