A couple problems that I saw I missed a depot around 60 supply and then later 160+ supply.
Did not get Ghosts or Vikings early enough.
Didn't expand to a fourth early enough and never took a fifth.
Might not have put down as many barracks as I needed.
Not sure if sacrificing half my army to kill that Nexus was a good move or not. I think it was a good idea though I shouldn't have tried to target the Collossi down and should have microd my army there to get the maximum effect before it died.
Please take a look and let me know what I need to improve on.
