Well, build and destroy is always very playable. In fact, too much building for my taste since it took me a while to collect food. I like the fact you disabled researching the titan (which would make it too simple), and omniscence. Suggestion: maybe requiring the player to collect all those relics in order to advance may give the player more incentive to explore the map.
The attacks on Kemsyt's site were too weak. Maybe having a little bit more AI to build units continuously would have put more pressure on the player. Also, once I had enough firepower all it took was the "loop" button to send elephants to Amanra's place and you know what elephants do in a china shop...
Also, I didn't even have to go to where the temple was since I got meteor for my mythic age power and you revealed the temple's location, all I need to do was direct it there.
The titan (being stupid and slow) was easily lured to the eastern corner with 5 or 6 villagers and didn't figure too much in defending my assault on Amanra's camp.
It looks a little bit like you started with the map first and then built missions around it--which is OK but then the map's creativity somewhat limits your imagination as to what the player needs to do.
Maybe limiting some resources (gold/wood) might help.
Map Design: 4
Not too bland, functional, some nice details (e.g. getting some wood for destroying the farm in the western corner, hidden Setna and all those relics).
I still don't get it--Amanra has a twin sister? Instructions were clear enough--kill the twins. A little bit of cinematic would help explain where her twin sister all this time away. And that Roc by the temple--maybe the twins can use it to escape once their health got a little low and you have to chase them to make it a little bit more challenging.
