This was my first ever game. I made it in my senior year of high school using C++; I was done with my assignments so quickly that the teacher let me use the extra time to make a simple game. This game is entirely text based, and features multiple endings. There is also a secret ending you get by inputting a secret code found in some endings.
The overall time spent will likely be less than half an hour, but I am proud of the world building I did.
