So I've worked on this game for a while. In my humble opinion, it's great; people who like this type of game are going to really like it, and keep it on the phone for weeks or months (forever, if it wasn't for the damn 'space getting low'). Yes, I know it's possible I'm completely wrong about it.
Now, I'd like as many people as possible to enjoy it - BUT I'd also like to make a bit of money from it. Not a lot, you see. The problem is that those two goals of course contradict each other.
I think a great solution would be to do what some music folk do - download the game, pay as much as it's worth to you, even after downloading (before downloading, you can't tell what it's worth to you!). Android Market, though, does not support this feature.
Maybe there are different ways around it - somehow get a sponsorship from some company, so the game is free for everybody.
Maybe some kind of embedded ads - really, how much can you get per click?
Maybe offer the exact same all on Market four times, at different price points (one of which would be free). Could you even do that? Same package name (so the player progress would be saved if you switch), same everything, just a different price?
Maybe there's a completely different solution.
