You might have made the mistake of actually expecting something for that $20. In my mind, giving money for a game (or any sort of kick-started concept) is literally a donation. And if you happen to get anything out of it at the end, even better. Granted, the developer also told you that your $20 would come to mean something. So that's on the borderline of being fraudulent (though, innocent because it was their intention to fulfill). The $20 has totally tainted your view of the product. So that's the bad part in all this, that you would not give another $20 to another fledgling video game kickstart.
