It was definitely unfortunate, Itch servers got a bit buggered during the upload period.
We will do an upload soon anyway so that the game is at least playable, just have to wait for the voting period to end.
We made a horror game in which there is only one light source, we didn't quite get the audio in, some stuff is janky, and the game does not have an ending, but here it is, we are currently on 9 ratings.
One important thing to keep in mind is that the light gets brighter the farther from the ground it is, and can be thrown straight up.
In our game, "A Light in the Dark", the hands were too small and were placed very close to the camera because of that, and when we added the lamp, it was either way too small in the world or way too big in your hand, so I just made it change its size as you picked it up and dropped it.
Also, for enemies noticing the light, I wrote some math that calculates the light level, but it was not at all accurate in actually calculating the light level. I called it good enough when I got the output number to grow as the light got brighter.
Our game is a horror shooter https://itch.io/jam/gmtk-2019/rate/463759
