Well... I just played that for a good hour before finding out there were managers who buy stuff automatically. I was too engaged in micromanaging stuff to realize there were more efficient ways to do things.
You should let us replay levels to earn more points or at least let us know what upgrading will give us. I thought the game was fun at first, but then the enemy just was way overpowered and I just had to give up. (this was on easy) Maybe I just suck, and I am sure there must be some way to get it right, but without knowing what things do, it is kind of like guessing. This just needs a bit of polish. I'll try again later.
A more efficient strategy than that is to send a crusader to the bottom lane and two hunters on the top and middle lane. on later levels I loved crusaders too, but to not run out on mission 4 you need to conserve crusaders for the end where their strength really matters
One thing that I would really suggest is adding a function to the library or at least somewhere so that you can see the cut scenes that you have already gotten to. The story is usually the point of a game and I just missed one of the cut scenes due to my computer freezing. It would also be nice to see how the storyline progresses. I think the logical place for this would be in the library
To get past horse guys, just use your shield until they are past and hit them from behind, preferably with a forward move so you can stay on their tail until they are dead. Also a quick way to get money when you get to a boss or even on a hard level is to select it, right click, choose play instead of loop and it acts like you won giving you the gold. You don't actually beat the level but you do get the gold.
Greek fire doesn't kill your own troops on this one. Get it to +10 and use the occult rune and you effectively have a nuke for a weapon. towards the end you don't even need an army to take out capital cities. You do have to take off your armor for the ninjas, but it makes the game a piece of cake.
I am sure that this is a great game, but I seem to have encountered a bug. On the first level I hit a troll and it gives me about 10 coins. Then I hit the next guy with his stone and I get about 1500 coins. Then I hit the third guy on level one and I get so many coins that the player just crashes. I am pretty sure that this is not supposed to happen because I also get an achievement pop up that is supposed to be for killing 200 enemies and I have only killed 3. I am playing on a firefox browser. Don't know what happened but I just thought I would let you know.
Another game to remind us to read the comments before wasting time beating the game only to find that there is a level cap. I really enjoyed the game, but finding myself just short of the skills I thought I was just about to get was rather annoying.
Good game, just some things to think about for future games would be putting the upgrade screen up after you die and before starting, also it was really easy since you could fly into a bunch of bullets and not really ever get hit.
For those who struggle with getting brilliant on levels with the ninjas just remember that they don't enter their "invisible" mode until they meet the first tower so don't just concentrate on building close to the gems. You also need them at the beginning to make it so the towers by the gems will be able to kill them before they touch anything. Once you figure that out, the game is really a lot easier.
