It's possible that people only support a developer because they want to get the game faster, but that's not the case for me for any of the developers I support. I support them because I want to see the game completed. For probably have the games I support (including this one), I don't even download each latest version, preferring to wait until the accumulated changes give me a significant new game experience.
I stand by my contention that more exposure will generate more support than more targeted exposure, but others are free to believe what they wish.
