This is a really unique concept and very well executed. I felt the inspiration from the TV show Chernobyl in the art style. It definitely felt out of control with the exponential growth of the reactor power and I had a lot of fun with it. Turns out I would be an awful Nuclear reactor controller.
Indeed you can say I was inspired by HBO's Chernobyl, but the show itself was quite true to the real life: see this archive photos for example https://i.redd.it/9wdqbcrsl1351.jpg https://pripyat-city.ru/wp-content/uploads/2011/03/1300896837_scn_0063-pr-s.jpg. I'm glad you've liked it :)
