Very nice take on the theme! I really like the idea of having to loop back into finding the items in the same levels. The flashlight mechanics also feel great! I agree with the comment that it could be even more important: you can only visualize items or enemies when using the flashlight.
I didn't fully understand how the loop acts in the game (the items are in other places, and I didn't see ways of using items collected in other runs), so maybe an extra explanation about that would also be good for a newbie at the game.
But great work!! I was really engaged with it and was eager to find out what was behind the lower levels :)
