Yeah, my schedule is about 3 months for each update. Keep in mind that it's just me making the game, I'm doing the coding, the images and writing the story. I also have my day job, so I can only work on the game in my free time.
Who knows, maybe in the future I can dedicate myself 100% to game development and release longer and faster updates, but for now my day job is the one that pays the bills, haha.
