The game manages to establish a minimal, yet good and fitting visual style. The game is overall pretty solid.
Perhaps a bit more work could've gone into the user interface: The controls feel sluggish as you can only go diagonally and seemingly have to press two keys the entire time and I was unable to determine what the colour coding of the boxes meant, other than the yellow and blue ones. Also, the random maze generator makes levels randomly jump between very easy and very hard, although that's a hard to fix issue and impacts the game just slightly.

The walking animation is really good! Unfortunately, the gameplay gets boring pretty quickly.

I found a small bug: The switch hitboxes are a bit too small, so that you can sneak around them.
