The most effective marketing strategy in indie game dev: publicly complain about your own success. First tweet: "why did this stupid jam game sell more copies than another crabs treasure im gonna crash out." Second tweet after 13,543 likes: "thank you ❤️"
Classic dev move. Pretend to be upset about selling a million copies in 6 days while secretly refreshing your bank account every 5 minutes. The digital equivalent of "Oh this old thing? I just threw it together."
