I like the idea, but it felt like there was a lot going on at first (though I think I eventually sort of got the hang of it). Some issues:
• It wasn't clear at first (until I lost that game and read the description) that you had to go back to the optical sensors to re-target (I thought it was just a one-time thing to make the outside visible), and kept clicking trying to target stuff and the robot kept walking back and forth. Also there was at least one time when it scrolled to make something else visible right as I was clicking and I clicked the wrong thing.
• Sometimes missiles just wouldn't launch even though the electron was shaking and the bar by the missile factory seemed to be full; not sure if there's some additional requirement that I'm missing or a bug. (Also, maybe more feedback of why a thing isn't working would be helpful? I also tried the EMP once and it didn't seem to do anything.)
• The game kept freezing for a few seconds for me; not sure if that's an issue with the game or with my 10+-year-old computer with multiple other browser windows open.
• Minor thing, but I wish I could use the arrow keys to go through the black lines on the circuit board (to the different sections).
