Simply amazing! Everything is top tier, congrats on the teamwork! The core idea is really great. Simple, yet effective. It reminds me a bit of Lethal Company for some reason!
The artwork is the first thing that stands out. The old style it has looks really great, and the floor layouts really remind me of those old dungeon crawlers with procedurally generated dungeons. All of those themes are really great as well for switching the game looks around. I also really like how the screen gets warped and darker when you get close to the entity.
I like that the game is pretty challenging, at least for me. Having the darkness follow you around, never knowing if there's something at the corner is pretty scary as well. The mechanics are simple but they work well. Simply with the dash and glowsticks you can maneuver around in many ways.
The audio is amazing. I really liked that you added some voice acting, I didn't expect to listen to any really! But the spotlight for me really goes to that eerie sound that the darkness makes, man it drives me crazy. I guess it's kind of a hum or sth from a creature. Idk but it fits it perfectly and REALLY gives me the creeps. Knowing that it's getting closer and hearing that frightened me.
