Hi, thank you so much for playing my game!
Don't worry, you are not stupid at all! The game does in fact end abruptly after the brief encounter with the "thing". I apologize for the game being so short but I'm really happy you enjoyed it. My next game will be much longer and it is possible that I will extend this game in the future to be longer and have multiple endings.
Thanks again for playing and leaving a comment! :D
