I just finished the last level in the campaign and got mass attack as a reward, which is pretty good. There are 3 levels, however, which I skipped after trying to beat them many, many times. Maybe I just have a bad approach, although I tried different tactics, but I could not beat the following three levels: Ovarion, Duneste and Blue Chilly Darkness. Time to move onto Multiplayer. ;P
I'd like to say that this is not bad, and if you keep working on it, you will attract more and more people.
There are a few suggestions I want to make. First of all, I understand that you would like to make money and that people do not appreciate that the way you chose to make it is, I quote, "just a stupid attempt to get you to pay for a basic game play feature". This might be one of the main reasons why people rage quit your game. In my opinion, make auto-fire at least, if not mass fire, buyable for iron as well as gold.
Second, another user mentioned that you cannot disable sound and music separately. I think this should be fixed as well.
A third thing I wanted to mention is the planet take over percentages. Currently when you attack a neutral planet, you get 5.5%. I think this is somewhat complicated for quick calculations, so at least make the dmg / shot 5, or even 1 and the needed damage 20. 1/20, 2/20..
I hope you look at these comments and try to do something about them.

Thirdly, I think you should add a list of the hotkeys (if there are any other than R for toggling run/walk). If there aren't, then you should inform the player at the start about R, because I didn't know about it until I read the comments. (Maybe you did inform the player somewhere and I missed it).
Fourthly, an option to turn off the tutorial would be nice.
Lastly, a very minor thing: when choosing the faces, there are two bald ones, quite far from each other, and at first I thought they were the same and I didn't continue to the right. I know this is very minor, but I think it would be better if the two bald ones were adjacent.
Again, very nice game.
I really liked the game so far, well done!
Here is a summary of my suggestions (for more info read below):
1. Difficulty levels.
2. Make Rogan be a different class based on your class (?).
3. Inform user about R for toggling run/walk and other hotkeys, if any.
4. Option to turn tutorial off.
5. Put the two bald faces (when choosing your character's face and name) next to each other.
First of all, difficulty levels. In my opinion (up until the water elemental, where I am currently), the game was quite easy; I didn't even use potions. (Except once, when I was wary so I used a HP pot). So I would say the current difficulty would be easy.
Secondly, Rogan's class. This is kind of tricky. You could maybe make him a different class based on the player's class, or maybe enable the player to choose teammate's class or maybe even remove him totally. I'm not really sure about this one though.
Very nice game! There is a bug though. It's on the level where you go through the glass tube into the house, then you see lights in the windows (you are going down a lift). On that level, you can shoot the ball so that you get stuck at the small wall between the two ramps. The ball keeps "vibrating" and you never get the next turn. 5/5
