This is one of my favorite pixel-platformers, for both it's theme and design, and it's moral objective.
A few days ago, I was on my way home from college when a man at the station approached me, wanting to 'introduce me to Jesus'. Normally I always let them talk while I arrogantly walk away from them. This time I decided to debate with him and we ended up discussing for half an hour, moving from religion onwards to 'Order vs Chaos'. He told me how in the end, Order is the right way and God can offer that. I started thinking back on playing this game, and described the elements to him. I might not have convinced him to back away from organized religion, but it did made me realize how much this game has influenced my ideas about the world, fate, morality, beliefs, order and chaos. Thank you for that :)
