Clever Concept in Theory but Not in Practice

Its a clever concept, but in practice, its less of a maze game and more of a puzzle game with very few puzzle pieces. Its almost never challenging, and occasionally it forces you to rely on trial-and-error (i.e. tunnels that lead to deliberately unmarked places), which feels like a test of my patience more than a game. It has an occassional fun stage, so if youre patient, it can be an okay time waster.
