1. Put a fort on each end with X amount of health. The goal is to destroy their fort and defend yours. When you defeat the enemies fort, you get a new battle field.
2. Don't make the battle field so long.
3. it would be cool if you could set spots where your troops would move to. Like when you buy, buy a group of say 5 guys and then that group gets a moveable target that you can move and drop and they will go to it.
bugs and shortcomings:
All I did was buy the gernade guys for 5 TA a pop and just kept buying them till I had so many blue squares started to appear on my screen because they stack ontop of one another, When they stop to fight or hit a barrier they should spread out. But I was getting blue squares because there were so many movie clips stacked onto top of one another. You can also just limit how many of each type can be on the field at any given time.
I started to get bored because all I had to do was keep clicking the gernade guys and went to level 20 and then I let them over run me just to see what would happen as there was nothing else to do.
Great game and I think you got a good concept, just build on it some. nice job
