The real problem with the multiple delays for Mighty Number 9 are that... no matter how good the game might be it will absolutely never live up to expectations for it's lengthy development cycle, and that is the problem with a lot of crowdfunded games.
At the end of the day.. this is basically just another Megaman, there is no way a side-scrolling action platformer is going to be deep enough or enjoyable enough to warrant the development cycle it's had. It's not like Shenmue 3 which will be a massive open-world RPG, or Star Citizen (which has it's own problems, don't get me wrong).
Think back to when the next big indie thing was Fez... it got delayed like 2 years, and yeah, it's a nifty, fun little game, but there is no way it lived up to it's development cycle, and half the crowd-funded games nowadays are exactly like that. They are neat little ideas, that will probably be fun games, but then they have multiple delays and developmental problems and a nifty little game that was supposed to be out in a year now turns into a 3 or 4 year wait for what amounts to a game with the gameplay depth of something from the SNES.
