Hey thanks for your feedback! I'll definitely take into account your gripes with sources of money. In the south east area, there are raiders which drop 50 Est every time they are killed, and they respawn if you go in and out of the area. So it is possible to grind them. There is also an alternative (weaker) sidearm that you can obtain straight off the bat after the introduction with only travelling one area outside Progress City. and yes, I will certainly fix the sounds. (especially the wolves)
Thanks for playing!
