I agree with Nisovin - this game definitely feels slow. I think the default movement speed for both the player and enemies could just be increased without adding sprinting. I also think it would be better to let the player attack, move, and shine the light simultaneously rather than being forced to stop other actions when starting one of them.
That said, this is a great little game! Nice artwork, atmospheric level design and an actual story, which is rare. Excellent work overall.
