Looks like someone turned the light off on you! Good thing you bring a flashlight around you at all times. The battery seems low so you must act quick. Press Space to turn on your flashlight. Use WASD to move. Point the flashlight using your mouse.
If you believe you are stuck press R (you will go back to the start) I used a faster version of my lighting engine This game optimizes for best gameplay. In that process, some detail was lost. To see a render with full detail see this project >> https://scratch.mit.edu/projects/301757630/
