No doubt! That's the main thing I'm going to be working on first, the lack of sound or any form of indicator for enemies behind you is currently really frustrating and leads to a lot of unfair deaths and that's not really what I want. I'm going to be spending a lot of time on this aspect to get things into a fair brutal difficulty range. It's never fun when a hard game feels hard just because you can't see the future hahah
Thanks for the feedback and thanks for playing :)
