In this episode of Game Dev 1-On-1, a Game Dev Podcast, Valentin Wirth joins me to talk about how he got into game development and how he’s building his first major solo indie game, Become. We go all the way back to his early fascination with games, level editors, visual storytelling, and the long path that eventually led him into cinematic and art-related roles on larger projects like Mafia III.
We also talk about what it’s been like going from AAA development to making a game on his own, and how Become grew from a strange but memorable idea into a real project with serious momentum behind it. The game puts you in control of a sperm cell trying to reach the egg, but beneath the funny premise is a surprisingly thoughtful conversation about turning biology into gameplay, balancing comedy with sincerity, designing a short and focused experience, and trying to make something that feels both silly and meaningful.
On top of that, we discuss how the game went viral, what it was like seeing the wishlist numbers climb, why Valentin is currently choosing to self-publish, how he thinks about sustainability as an indie developer, and what he has learned about pitching weird ideas, working consistently, and figuring out whether a game is worth committing years of your life to.
