The art is so cute! Love the minimal magical shadowy color palette.
I found it easy to win a couple times just moving randomly toward the exit in each dimension, without needing to think or strategize around the 3d map. (Or, maybe wandering toward the exit in each dimension IS the strategy.) If the maze were any harder it might be way too hard for a first level and lose the exploratory part, but I could see this being fun with multiple levels that are designed to start really simple to teach you how things work and then ramp up the difficulty until it really is necessary to think through your steps .
