It took me a while to figure out that I had to flip the "wires" 180 degrees, and that they didn't just have to fit together. There's also no way to know which wires are clickable, and which are not. I got stuck on level 2, having seemingly clicked all the clickable items to make them glow, but the lightbulb did still not glow. Tried clicking every piece of wire on the screen, but no luck. (Edit: I had to go back to the first level and rotate one of the ones connecting to the second level lines, then it worked!)
The concept is really cool, the graphics are nice and clean. With a bit of cleanup and some puzzle elements to it, it could be a really interesting puzzle game. Nice job for 48 hours tho! :)
