I really hate that Kickstarter system.
People get crazy and give lots of money to developers, developers want more money so they promise more, more features, more platforms, more everything and the project gets bigger, balloons and from a little reasonable indie game becomes unmanageable Project Manhattan.
Promising more features while keeping the same deadline is incredibly stupid. You won't miraculously do more work with the same people within the same time period.
Having said all that i still pledged for 3DS version.
