This Scratch program is very effective, it would be beneficial to primary school aged children as its fun and engaging. You are able to change the background as well as the character. I actually found this game hard to understand, it took me a while to understand how to use it. i personally would not use this in my classroom because i found other activities where a lot more simple and easier to use, but if my students wanted a challenge then i would get them to use this program. Similar to the Angry birds game, it has the codes labelled and ready to use, which makes it more effective and easier for students to learn about coding.
