A neat looking little puzzle game.
I like the art style and story combination with the theme.
There are a few cases where you can get yourself stuck with the only option being jumping into the light (how poetic that might be), which is a bit annoying to have to do.
Additionally it is sometimes kinda hard to grasp what buttons do when the light it switches is off-screen, maybe add like a wire in the background that runs to it?
Other than that, nice job, well done :)
