I want to make a game

I am currently playing Undertale, the game that Toby Radiation Fox made in 2015. I played it once before so I knew what I was getting myself into. The music was amazing and I loved how each boss battle was interesting. It gives me fuel to make my own game. Like what would a dragonMaiden game look like? What would it sound like? What would its story be? I’m going to spend some time making a video game concept album and brainstorm ideas. I want the music to play a large part in the story and also have other sorts of gags.
