This year’s GGJ theme was the first to be non-visual. I wanted to stick with this theme in the game Pulse. The world has fallen into absolute darkness. The light that shone from once pure hearts has faded. Only their Dust remains. You are one of the last remaining Strong Heart. Only Strong Heats can collect the Dust. You must navigate the dangers of the dark world while gathering the Dust to bring light back to the world.
