Good puzzle game with a good progression curve for me. A bit confusing to figure out what to do. A good idea for next time is to find some way to tell the player the controls and what they control. It took a minute to figure out that it was the maze itself.
I also often lose track of what I was doing and which direction the buttons moved. Maybe the game would be easier to follow if it's the dots, and not the maze, that moves. If you want to continue working on it, I would recommend trying some different things to see if you can make it easier for the user to understand what is going on.
