I have lots to say about this game, so it's going to be a long one.
After playing the entirety of Dimentia, I saw several lessons implemented into each level, the biggest one being about breaking the cycle of negativity with positivity. If it's true that the ones that ended up in Hell are at fault for their own sentence, then it's up to them to find the strength within themselves to drive away the darkness within themselves using light, using love to drive out hatred, charity to drive away greed, and wisdom to help them stay on the right path.
But that's not the only lesson. The ordeal with Caiman taught me that coders have lives just as much as everyone else, just like music artists and architects. To say that they should only live to work and not enjoy life would be treating them like robots, disrespectful and disregarding. Then there's the bullshitting god (as I call him), where accepting gratuitous amounts of punishment is not the same as redemption. If one truly wishes to make up for what they have done, it's better to fix what they damaged and promise to do good things in the future rather than damaging oneself to even the misery. No one wants even misery. And finally with the sky raid with Cleo and Petra, there's actually two lessons. The first is when choosing sides in a battle, one must see both sides of the spectrum to truly understand the reason for the fighting. And second, no amount of treasure no matter how valuable is worth more than the lives of others. Think about how you would feel if someone you trusted chose material goods over your life.
I'm a little saddened about rescuing pigs or collecting treasure. Not saying you did anything wrong, but I was led to believe that you could have multiple endings after you completed the sky raid and spoken with the pigs. Even after only rescuing the pigs to bring hope in one attempt and only collecting treasure to appease them in another, I still get the same result. It's rather disappointing.
All and all, I feel that this simple brawler has dispensed more wisdom than an educational game, because it's story is just that diverse. This is one of those games that needed to be made and played. Thank you very much.
Edit: I just came back to this comment 5 years later and... I do NOT like how I wrote my comment. Don't get me wrong, I still like the game and I'm keeping the score where it's at, but man did I sound so pretentious back then. It's like I was trying to sound smarter than I actually am. I'm really sorry about that.
