I like the unique take on the theme!
As for the game itself, it's a bit difficult to understand what is going on. I think the manual could have done a better job providing instructions. I tried signing in immediately, but then I got completely overloaded with tasks and quickly lost my job. Then I took a more careful approach, tried to stabilize the reactor at first, pushed some buttons before even starting the reactor, then I got 'Shift complete' message. Then I tried signing in again and noticed it's the tasks aren't just any red LEDs, they're blinking LEDs. I think I finally understood what the game is about then.
I think it's an interesting idea and it is presented very nicely. I liked the art style, color palette and sound effects. Well done!
