Prisoners Beneath the Sky

Ever since I was little, I've wanted to play a game that could simulate physics and chemistry. I was fed up with how every game on the market felt the same, with boring damage and healing systems based on elementary-school arithmetic. But even over the past decade, I haven't seen a game that would satisfy me. So I'm writing a game novel here for my younger self. I welcome any feedback on its shortcomings. (I don't have the skills to make a cover, so I'm using a template for now.)
