Just beat HL: Alyx. Really enjoyed the hell out of it and I'm so happy I got to experience that ending without spoiling anything. Don't have any major complaints, but the grenade throwing was very inconsistent with the force needed for the throw so I'd often either launch the grenade 100 miles away or do a fair chuck and have it land right next to me. 

The disconnect with the jumping took me out of it sometimes too but I'm just glad they put in walking at all. All I can say is I'm excited to see where this goes now.
