Not all games can be free, if anything you're the greedy one. People don't just pour hours and days of their life into a project for free. Maybe I'd understand if the price was absurdly high but its 3 dollars. That's a pretty low price, its not that hard. There's plenty more hentai games that cost more and don't have a demo. but you have to pay for those games, and I guess that makes them greedy.
