I didn't know that you could do this shit! I would've loved playing some games on my calculator back in the day.
I actually programmed my own game over the course of a few weeks of boredom in class. It was a text choose your own adventure game, where it would just give a sentence and then a few choices. I remember a few people would ask to borrow my calculator in class so they could play my gem.
I don't remember much about the game other than you were a man who woke up with amnesia and you had to find your identity. In the twist ending, you find out you are actually Hitler and you lose anyway.
