For my master's thesis, I have decided to create an audio computer game to educate players about how visually-impaired people use other senses and abilities (like echolocation) to get explore and visit new places. I am concluding the research portion of this study and will start development soon. However, the only coding languages I know are HTML and CSS. I've created game on GameSalad, but this game will be more complex. What game engines are simplest to pick up and have strong tutorials? (Side note: I originally was not going to do a computer game, but COVID has forced me into this option.)
