Finally defeated Computer at 850

Can someone analyse this game? Constructive criticism is highly appreciated.

2.e5 is a poor choice, 3.Bxe5 or 3.dxe5 would win a pawn for white.

3.Nc6 you could have grabbed the pawn with 3.exd4.

4.Nf6 you could still grab the pawn on d4 or grab space with 4.e4. Instead you lose the pawn on d5. 

Computer plays bizarrely, hanging a bishop and a pawn for no reason... 

10.f5 is not good, d5 was hanging. Better just solidifying with 10.c6.

Computer hangs queen for no reason... 

Computer hangs knight for no reason... 

27.Be4+ was utterly crushing, although it's not a contest anymore anyway. 

Computer goes kamikaze hanging everything....

Some loose play by you in the opening, hanging a pawn, failing to win a pawn when given the chance. Later hanging another pawn. You must take care of your pawns - a good player will turn an extra pawn into a win. I also urge you to play human players instead of the computer because a low level computer plays unnaturally. There is no way an 850 rated human player would give away their bishop and queen as happened here. Its not good practice for facing human opponents and improving IMO. The best to you in your progress 👍
