I'm convinced that mine has gone awry somehow? Why else wouldn't the pink block in the center island not be doing the same thing as the pink block on the bottom-right?

Anyway, despite being unable to finish this, I thought it was good in concept and am eagerly awaiting more like it.

Holy hell, I usually think of myself as good at these sort of puzzle games, but I just now finished this one after giving it a lot of thought over the weekend and then some. Many players might be put off by having to figure out how things work as you go along, but despite some initial frustration I got to like it and appreciate the adventure once things started to click and am amazed this was just one among the game-a-day series. If/when you decide to switch to making something larger scale, this should definitely be included in its inspiration.
