The speed change felt a bit inconsequential unless it got set very low. I felt like the ammo was a bit generous as well since you can corral them up and throw a grenade. There's definitely still some intense moments when you can't move fast at all or when you keep eyeing your ammo count and the time and trying not to run out of ammo beforehand. A minor gripe I had was when enemies would spawn very close to me. It felt like I either couldn't react/kill them in time or if my speed was slow I couldn't evade them. Overall the I felt the game had its moments but could have been much improved with some minor number tweaking.
