There was practically no use of the jam's theme, but as a separate game, it was good. It was simple, but that made it fun and kept me on my toes. If I were to change anything, I would add more visuals (even if that's just some patterned background with geometric shapes or something so that you can see things move past you that aren't the platforms), coyote time, and the ability to restart the level quicker as I typically want to try again quickly. I like how you made the black fade in though, as it adds mystery, but I think the restart button should fade in with it at the same time. The music was good and suspenseful, but very repetitive and since the only sound effect seemed to be the dying one, that got repetitive as well. I like how the spikes didn't instantly kill you, however, and instead slowed you down as it adds to the main focus of escaping the darkness.
