Good,
-Terrain impovement
-workers cost improved (even if it would be better 4 instead of 5 food, 'cause farms give 8 food)
-added new hero
-hero revives the next turn if dies
Other problems:
-I noticed that, if your hero dies, or inventory is full, the ank will go near the king, wich can pick it up and revive if dead;
-if someone in your team leaks, you got to run to take the leaks, and not always you are able to reach them;
-if you are defending the king, you ain't got much time to go back to your position;
-some skills are unbalanced;
-boss levels are too difficoult;
-you can go in the spawn zone, so you can use your skills to nuke spawns, without getting attacked;
-you can attack your king (don't know if can attack allies too);
So, in my opinion, you should:
-pervent the king from pickin' up items;
-add a teleport sistem;
-review some skills (for example, passive skills got too much % chance to work, or other ones cost too little/much mana in comparison with others);
-adding an item shop wouldn't be bad;
-dont know if it is a good idea, but make creeps in the spawn zone invulnerable;
-make farms upgradable;
-don't let the heroes attack the king;
-an arena after each boss would be nice i think.
