I'm sorry your daughter did not find my little game fun but I am glad it has fear vibes.
The lighting is not the final balance that I intended but, you know, game jam pressure. It's not entirely black (mostly) and if you use the flash from the gun to find your way guided by the hand prints, there is relief from the dark when you complete the objective, just stock up with the spare ammo first by loading it into the gun, ejecting and loading the next one (I meant to add more ammo by default, but, game jam time).
