After it took me some time to figure out what I was doing, I have to say this is a great concept. Truly original idea I would say. The puzzles were good, but the difficulty increase could maybe balanced a little bit better. The 2nd level for example was one of the harder ones, as I had still no idea what to do and suddenly those blobs can kill you.
For graphics I would say that sometimes it is tough to get a good overview. Especially in the buildings, the different floors and rooms visually just block the easy recognition of the wires. I don't know how, but it would have been easier to get a better overview of the wires.
But those are just details and the main part is, that the game play just feels good
