How the hell do you beat the last rescue, I genuinely have no clue
It's certainly the hardest puzzle! Here's how I do it...
Use Apple Units to "build an engine." (1-10 Runs)
Seraphim Units tank hits, and Cherub Units have piercing attacks...
You don't need to kill the enemies, only the seals in the back!
Good luck!
Don't the apples die once they get in range tho?
