Like nico said, very few people will actually get this game. It's only fun for a small crowd. To everyone else this is a waste of time. To top it off, sometimes the backgrounds make the text hard to read. Stick with one background or use a larger font.
The enemies quickly overwhelm you and you're not given much of a shot at fighting back. The menu is also really obtrusive. The game lacks sound, music, an appealing battleground, upgrades, etc. But I'll give it a point for the path changing system. That's a good step forward.

The bosses have waaaayyyy too much HP, the spell respawns are a little too long, the green mages are too powerful and your respawn penalty is too high.
This is pretty much a rip-off of Wrecking Crew, the old NES game. It's even got the same music.
It's not a bad clone, just a bit dull. And why do the other guys climb ladders at mach speed?
I don't get it. I can't even win a skirmish against a single opponent. No matter what I do the computer always has more units than me. Even if we build the exact same things at the begining of the match, somehow he's attacking me with two ships before I can finish building one and he just keeps hitting me from there. How is this easy? Or even fair? What am I missing?
This is awful. Why can't I build all the way across? And why can I sometimes connect two rivets on one side, but not on the other? This is like a poor version of bridge builder.

It's like an even more boring typing test. The only way you can lose, it seems, is to get hit by the letters, which are really slow and easy to avoid. Like the others said, you also need to stick to the left side of the keyboard.
I'd suggest sticking with W-A-S-D for your letters. Then speed the game up, add power-ups, bigger clusters of letters as boss enemies or something, and make a penalty for letting them escape.
