I didn't found the flashlight initially. Only after reading the comments and restarting the game I did.
The collider for bugs with red eyes seems to bit too big or something, I always hit it when jumping on top. I was also wondering why the eyes are not visible in the dark without the flashlight. But I guess its like with cats or other animals, that its just reflected light.
Yes, with some creepy music it would have 100 more impact.
Wonder how it would work if the flashlight would be following the mouse rather then using keyboard for it.
I liked it, good results, looks like you put good amount of work into it! Well done.
