I'm glad to hear that some of the negative aspects of this mod I have experienced have already been fixed or at the very least are being looked into, very encouraging news!
I genuinely hope that you will consider making "fast monsters" optional as opposed to being on by default for Serious Difficulty though as I truly think most of all the balancing issues stems from it.
At any rate I hope that I have provided some useful feedback in my videos despite my negative rants at times. I really want to see this mod succeed as there really isn't anything else like it available for the Sam franchise. This mod has so much untapped potential and I wish nothing for the best for you.
I will eagerly be awaiting any new version of this mod available to be tested!
