I made it about twice as long as when I played source, about 45 minutes. It seemed hard as fuck to see anything. Recently I saw this (watch the whole thing)
It seems alright other than that. IMO molotovs are a cool addition. AWP is annoying; the time between when you stop moving and can shoot straight is a lot longer than in 1.6. Deagle is overpowered like css; you can even shoot accurately with it on ladders.
