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.
