Prototype1.0 of Quantum Maze

I make the game for an internship of quantum computing. I need to create  a game which make use some kind of quantum computing mechnisms. And it needs to be educational. This is quite chanllenging.

Finally I decided to make a puzzle game with some maze mechanism. And it is quite to tackle the state changes.

And as I am not a 2d artist, I have to learn the 2d artist on the way and I think the art of the game can be polished. 

Just want to get some ideas on how to improve it for a better playable game which can be published to Apps.
