Admittedly, I spent like 3 minutes on the first level just trying to figure out how it worked. I had every single cell shaded in blue and was spinning the outside like a maniac and nothing was happening. For some reason, erasing every cell and then only painting the cells I needed blue is what solved the puzzle, but WOW did I spend some time pressing every button and spinning everything I could.
I think it's a cute concept! I love the aesthetic of the maze in the middle and the scribble sounds.
