Woow! That's like the best review one of my games has ever gotten! Thank yo so much! It was amazing to read!
Some of the sounds might sound different from what they're supposed to convey because I used sounds that convey something else hahaha. For example, the car engine is actually a chainsaw. And the doors are actually...ummm...I don't even remember.
Regarding the long hallways....there are 2 reasons for this. 1) Preparing the player for an upcoming enemy encounter and 2) for filling purposes. I had to fill the maps somehow hahahah. But I will keep all of this in mind for my next games.
Thanks again for your comment! Your feedback is really valuable and it will help me with my future projects!
