Awesome!
This game is great. The beginning was kind of boring, but the more you play, the more fun it gets. Hope you make epic war 4! And here is some constructive criticism:
1) Music.
The music is cool, but could there be 2+ battle tracks? It is boring to listen to one track for a long time.
2) Cursor.
When casting a spell, the white cursor under my own cursor is just weird. Either hide the default cursor or remove the white one.
3) Lag.
Remove the max population of units or something, because the game can get really laggy.
4) Castle health.
Seeing it would help a lot.
5) Opponents.
It is as if i was playing alone. I never got attacked. They just mostly skipped their phases.
6) Buttons.
Maybe the retreat and forward buttons could be held down somehow. That would be awesome. It is annoying to click forward all the time.
7) Upgrades.
Perhaps you could see what happens in the next upgrade before you buy it. That way you could decide which upgrade is the best one to get.
