Thanks Gil for the feedback. I did notice so control issues, even moving horizontally had a slight deviation from 90 degrees, but I didn't have the time to fix it up. My current project I have fixed that issue.
The strange gray noise was actually intentional! I took it out and replaced it, but it gave it a bit of a hollow, haunting, creepy feel to it as you wander around the maze(s) getting darker. I soundtrack that quickened as it darkened and slowed as it lightened would have been a great 'atmosphere'. Definately could have done better on sound though, but sound does tend to pop up in the end though and suffers accordingly!
Thanks for the info, appreciated.
