A tame ending

I played as white in this game against computer(~1600) which appears on chess.com main page when it was down .

This game was equal till last stages when suddenly computer committed blunder.

Let me know if you see I missed any tactical shots and if I played any bad moves.

Thanks!

You made a couple mistakes if you want analysis of a game you should just submit it for computer analysis.

I find 7. Bc1 odd since you could have played 7. b3 (which you played on move 10) and left you bishop active. 

Also, did you notice that you played 2 Nf3 and never moved it again?  You never moved your light squared bishop after move 26, either.  I would have tried to activiate one of these pieces on move 31 when you admitted that you didn't have anything better.  Nd2 then Ne4 may have worked. 

Nice win though.  I can't beat the computer on here. 

Apparently it forgot after one move.

Thanks planeden for your analysis.
