For the very first episode of The Shmup Talk Show, Zirolux sits down with DrBossKey, founder of Uplifting Goat and creator of Interstellar Sentinel and Interstellar Sentinel 2. What starts as a conversation about indie shmup development quickly turns into a three-hour-plus deep dive into game design, arcade history, storytelling, cyberpunk influences, fighting games, development tools, community building, and why shmups continue to inspire so many of us.
