very interesting take on the idea. there's certainly a lot of room to explore game-design wise here, and I do like the level design. I know you included a tutorial but I appreciated the levels actively forcing me to interact with a mechanic before testing me on it. It seems obvious but lots of people forget to do it.
I personally think the movement is a bit too slow. Additionally, it was very difficult to actually remember what my button inputs would be doing after touching some symbols, leading to me pressing the wrong inputs some times. I think this could've been alleviated by having controls for each character on screen in some way. Its possible that confusion is just inherent to the idea though.
Good entry!
