Tbh I don't blame him for wanting to cash in on the success of it. He's a single dev, and while he's had some successful games (like Iron Lung, Dusk and Chop Goblins) I totally get that bills have to be paid and if raising the cost of a "meme game" by a couple bucks helps pay the bills, then the choice seems like a no-brainer. Besides, at that point most of the people who were going to buy it had probably already done so.

Note: I call it a "meme game" not because its bad or a joke, but because it's literally become a meme in the traditional sense.
