To beat last level:
- Max all upgrades / levels
- In the front - 10 swordsmen (1st unit)
- In the middle - 10 beer guys (3rd unit)
- In the back - 20 Thor guys (last unit)
First wave: use thor and arrows (ship)
Second wave: use beer and swords
Third wave: use stone (ship)
After this I forget what happened but at the end I was saved by ship arrows.
Fourth wave: use thor again and arrows (I think)
Fifth wave: use everything

Best strategy I've found is to use the thor / yellow hat guys (strongest regular unit). Just keep upgrading them and mass them, easiest wins. The rest of the units are useless, don't waste your money upgrading them
For the last level on hard mode: Make sure you take over enemy battlestars ASAP. Use the warp holes so your ships don't get destroyed. Try to mass one super strong stack (around 300) and fend off Black for a bit. When they are weak enough, go for the center star and you win!

Basically you just need to get lucky and get a high score earlier in the game when the squares move MUCH slower... Keep trying and eventually you'll get a game where the squares just seem to stick together more.
It's easy after you get figure it out.
For the larger targets, stay behind them and creep up on them slowly. Turn around before you are within their firing range, rinse repeat.
For darts: they are annoying. Either use speed to loop around them, OR get in front and gas them. OR a combination of both. If you have more than one plane, use one as a decoy (but keep evading using speed and turning) and the other to shoot it down. "never leave your wingman"
