You did a really cool thing with the interactive elements of the game. For a lot of games in general but especially in Bitsy, the player usually feels the need to find every interactable object in the game so they can observe the entirety of the story. By making most figures disappear whenever the player walks over them, you're subverting the idea of exploration by providing it with a negative outcome. Grouping that with the fact that the player avatar is designed the same as the soldiers that come in the "last" room, you've done an excellent job of communicating a message with the minimal visuals that a designer can get away with when using the Bitsy engine.
