Neat Submission.
Nice art style. Really good job on the Audio in particular though. SFX sound polished, Music is fitting, and gushing wind really adds to the experience. Overall, you've built a game with a really good atmosphere and feel to it. Ticks the Theme box too.
For improvements, movement could feel a bit slow at times. Maybe add a sprint key/button. I'd also recommend switching from hovering cursor over ghosts to using a Ray of Light approach where any ghosts in the ray are damaged. Would make more sense given its a flashlight.
Overall, good submission. Well done!
