Awesome game! I found one issue though. It really ruined my experience. There's a typo in the description of the Pirate Flagship! "There" should be "where". Totally messed up the whole game for me. I could only play for like ten hours or so.
How to win:
Step 1: Ignore the tutorial. Your soldiers will gang up on single units, letting other units past if you cluster swordsmen at the path entrances.
2. Spread swordsmen out along the paths, focusing where multiple paths converge or on entrance points.
3. Place archers where they can fire the longest, i.e. in the middle of a path square moving around them. Treat swordsmen like slow towers, and archers like ranged towers as if this was a traditional TD.
4. Cluster swordsmen at the end (three or four should do it). If you've stretched the defense out, then the only units that should make it to the end should be the strongest ones. While it kills one swordsman, a second or third will respawn and engage, keeping that strong unit pinned.
5. Pray that your archers actually shoot at the air units.
Hope this helps a bit, it's gotten me through most of the game.
Interesting glitch on level 3...the plane on a wingman's six turned out to be bulletproof. No wonder the Luftwaffe was so tough, they had invincible planes!
