I love that you have a README and License file (main criteria for open source category). Next step would be filling out your README. You can add information about the game, screenshots, and even just take what's on your submission page: https://pgad.itch.io/presidents-red-cap.
The sound effects are lovely and chill. You put a lot of work into the narrative; love it. The art style is interesting and fits nicely in with your game. It'd be cool if you could also just press anywhere on the text bar to select the option you'd like rather than just having to press the red paper plane.
Great work on your submission. It was a lot of fun.
