I ended up using escape wings exactly twice. Once you're past level 30, nothing can touch you. I also only ever used a handful of large health potions.
The best part of this game was bisecting dummies with platforms or crushing them and watching pain shoot into the millions. Which doesn't bode well for the actual gameplay.
Sniper towers with 8 reload are lulzy enough that a single tower with shock support beat the rediculously overpowered wave 50. It was a slideshow, though.
I've also received perfects while damaged at the end of the day. If you kill a ranged enemy after you take damage but before their firing animation finishes and the projectile reaches your castle, it seems to count it as not getting hit for the sake of perfect rounds.
Matty- duelists get bonus damage for keeping their adrenaline up. I fire 4 or so times a second, so it's always full, and that makes me do about double damage. I can kill tanks in one shot with a revolver.
