This was one of the easiest "Impossible" badges. It just takes a little bit of practice to learn the patterns and to make sure you keep your combos going.
The hard badge isn't really hard at all. Once you get the last three upgrades and the 2nd skill, your team is invincible for the most part. The skill recharges fast, which heals your party constantly. And once you learn the patterns of the waves, it gets really easy to maneuver yourself into a safe position.
I dont know if this is a glitch, but I've beaten Down and Over on Normal mode like 5 times, but it doesn't show that I've beaten it, thus it doesn't allow me to move on to the next level with Normal Difficulty.
Sometimes I dont get it. I'll build the perfect stack of pancakes and get 99%, but then when I have syrup and berries falling off the plate, I get 100%? I'll have to remember to some special sauce for those people who can't appreciate beautiful platting techniques.
