It's a cute game. The little challenge of optimizing the movement paths so you don't get in your own way is nice, and the little challenge of the machines being lined up suboptimally makes for a reason to route with intent, although with the limitation of four machines and the small room means that you quickly hit the end point once you get your stride. The fact it runs entirely in browser and doesn't require a download is also very neat.
Looking forward to seeing this idea in another game! I like it a lot, it's got some real potential.
