Thank you for playing! If you reached the ending credits it means you finished the game. Sorry if the final part was confusing, I wanted to be ambiguous, but maybe not that much. I think you can create yout own theories now.
Keep making games, jams are a good opportunity to get feedback, meet other developers and learn. Don't forget to make the games you'd like to play, putting in the shoes of the players is one of the best ways to know if some idea is working or not.
