Love the minimal design, the changing colors, and environments that are affected by the player's movement. Using the spotlight definitely increases the difficulty of the game and the player has to "go die to explore". BUT that is also the concept of the game, to rebuild our self, by exploring, trying, and collecting. However, I think it is a bug that sometimes double jump doesn't work, so it is neither your keyboard, nor mine that is broken. Perhaps it's because the jump addForce is put in fixedUpdate that some frames won't read the player's action (that's a problem in my game so I use update then). Also, the background music is set only play once, perhaps let it loop because players like me would spend more time on the game to find the path out.
