In terms of "I could pass it," even setting aside the fact that a lot of the beatmappers here are on a higher playing level than the majority of people who might find this program - especially with the Joystiq link - I read a piece of advice on game design once that stuck with me. If you're designing a level or something, when you get to the point where you've made a level that you can complete, stop and make it easier - because the player will always find it harder than you do. You designed the level, you know what's coming, and what you were thinking when you were making it - the player won't.
