A bit messy in presentation
You really could've worked on it a bit more, I mean, you just used, what looks like, picture cutouts.
Also, the game needs more variety, such as more units, such as horse cavalry, or generals that boast effectiveness, ANYTHING, I mean, seriously.
If you make a game of this type again, note, do not allow everything to be built immediatly, make it so that you have to spend money to make them available, or something.
My favorite thing in this game is the infantry spam, it's possibly one of the funnest infantry spamming I've ever seen in a flash game, with these swarms of guys all making a mad dash.
Another thing though, give the fort and ships less health, it took forever to destroy them, I'm pretty sure a fricking cannon knows how to tear through wood.
