Very fun! I agree with some other comments about the item transport, but I don't think it was too bad until the machines started to get packed in more densely.
Thanks! They're all randomly generated at the moment, but I've been wondering about making better puzzles with a manual setting. Or learning from that to improve the random generation, anyway.
Thanks! The levels are randomly generated, but it builds a path backwards so there's always at least one solution. I tried (for way too long) to make the boards always have exactly one solution, but it was getting a little complicated so I had to scrap it.
