I played through 15 of the 50 levels, taking about 10 minutes. Based on the images and description I was hoping the game was based on logic gates or circuit components. Unfortunately it ends up just being a game of very simple nested mazes. Solving a maze involves tapping on the switches repeatedly until they go where you want them to go.
As another reviewer noted, the switches have various states, but have no consistency about which are available, nor any visual indications. This means that you have to go through trial and error to figure out what tools you have available each level. And unfortunately that just exacerbates the tedium of progressive mazes. Minimalist is great, but not at the expense of useful information.
I really don't have too much to add from the excellent and constructive review by "Another Game Person". I had hope for the game when the first level that had multiple lights appeared, expecting to have to light them simultaneously with a splitter - something like that could become interesting and potentially diabolical.
