My Take
I thought this was a creative teaching tool. I liked that it allowed for puzzles to get more challenging if a student got the previous one correct. I think it could benefit from some more instructions for the students, at least at the beginning.
How I Use It
It would be great to use this app with students during individual learning time. I would also use it as homework; students would have to complete one or two levels and then write about the experience. For younger students, pre-K and Kindergarten, I might create a center that would focus on problem solving through playing this game.
