IMO, the game was unfair -you were Set with bonus for slingers, and he was Hades with bonus on archers. Your slingers won all the battles, up to the point where he came in with lots of Collosoi.
You stuck with building slingers, and didn't make more priests until late.
Of course, he destroyed your Midgolds where you should be spamming elephants instead of chariot archers.
Your force of archers should've raided and wiped out his vils.
Your Tornado, should've been used on his base to wipe out lots of stuff there, and not on the force of gastraphetes.
Your starting priest, should be converting animals with which to scout/raid.
You forgot to make houses, so your pop growth was usually halted -cause of the animals coming out.
Last, the map was fishing and not hunting.
I saw myself playing there, a purely defensive player and so I know we make the same mistake.
The name of the game is attack, kill his vils to disrupt his production and put him on the defensive, while your eco grows.
I advise you to go to AgeSanctuary, and dl expert Set recs to see how they do it.
