Good job. The black material on the platforms makes it a little difficult to gauge direction and jumps. Using a lighter shade that stands out against the walls could make it more intuitive.
There's a cool risk vs. reward thing going on with this. Good job!
One thing I learned with working with Unity Sprites: In the Sprite Inspector, you can set the filter mode to "Point" to keep your pixels nice and crisp when you scale up the object.
Thanks! The actual difficulty was definitely an afterthought. If I go back to this, I'll probably add randomly spawning batteries that need to be collected to keep the flashlight going, rather than to make the player keep clicking.
