Yeah, no worries, I realize it's just early stages, still wanted to post my feedback :)
Not sure about the runway darkness, it does increase the uncomfortable feeling, but it's also bit annoying to not see everything. So I'm not sure, depends on your own preference I guess. And there's a brightness option in the menu, so you can use that.
About the weapons, I was just surprised, because you had them as pickups in the previous versions.
Ragdoll always looks nice, but I would consider it a low priority, first focus on the gameplay, physics and levels would be my suggestion. Ragdoll dead zombies would be purely visual and I can imagine it would take quite some effort
