Description (written by the developer; not a statement by this register)
This is a prototype nuclear fusion black hole antimatter reactor developed by the Mirin Science Group. / Congratulations on becoming a staff member at this facility located on a mountain in South Korea! In case of emergency, read the emergency evacuation text in the image. / Now, shall we get to work? - This game was made by Koreans, so some English sentences are awkward. / And there are only two developers, but there are too many things to do, so it may not be updated.
