I hated this series, but after finally understanding the dark yet tragic truth, behind these games, I realized it's so much more than poor quality meeting the eye. Customers are almost always the same people across games? Louie mysteriously leaves with no explanation? Life outside of the restaurant is never shown, so you can only assume that the existence of your character merely begins and ends there. Customers are able to order whatever on a daily basis and don't seem to ever be at risk for health problems? All the things together leave me to believe a much more tragic element is at stake. They are already dead and in some type of gluttony related purgatory, where Louie intends to trap the souls in such a way they may never move on. Was it because Louie never made it as a chef in his mortal years and desires to hold on to customers by any means necessary? Could he be a demon who simply enjoys the struggling of others? Nobody will ever know for sure.
If your computer sucks as much as mine switching the quality to high actually makes the survival run slower and easier to react to. Things to note, is armor does spawn in survival if you need one otherwise it won't appear. ALWAYS try to get armor if you see it since you don't know how long until it appears again. There really isn't much for elaborate strategy for survival. When I did the arena, I found the engineer to be more dangerous then others because his attacks track you. But if you already perfect ran the bosses before you already know how to evade their attacks. Save Dark Zoul to the end obviously. His attacks are random but easy enough to avoid in his first stage before he's hurt. If you kill the other two, it's just him and it won't be anything you haven't done before.
Honestly, I'm pretty impressed at the creativity, how they can take what is just a ball and lines and make every level unique so it never feels like just the same.
Dragon: "Give me gold or I will eat your people!"
King: "Hmmm..."
Dragon: "W-what is there to think about?"
King: "....like a lot?"
Dragon: "Wha-yes! I will kill a ton of your villagers!"
King: "Yeah...that's bad...but you will leave that imp and living treasure chest alone, right? Almost every week they pay me so they can kill villagers."
Dragon: "Y-you're a monster!"
King: "Oh god. The tree people didn't send you did they? "Ahh! Stop cutting down our home! Stop turning my brothers into furniture! At least get your feet off my head!"
Dragon: "I...I'm going to go. I'm going to be sick."
King: "Are you sure you don't want to eat anyone on your way out? It's not like they pay taxes anyway."
