What an original concept! Using your own voice to interact with the game is already a really interesting mechanic, even if we've seen similar ideas in other games. But combining it with a mysterious atmosphere, dark corridors and ghostly creatures is such a clever twist! I think it adds a whole new level of immersion, making you feel like your voice is actually part of the world rather than just another control. A really creative approach to horror and exploration. Great idea and great work!
