What drives someone to spend eight months building their first shmup?In Episode 2 of The Shmup Talk Show, I sit down with SealBro, Director at XtraSoft, to talk about the development of Emerald Blue, one of the standout indie shmups of the past year.We get into the origins of the project, how a small hobby team turned their passion into a commercial release, and why they designed Emerald Blue with beginners in mind without sacrificing the depth that veteran players expect.We also dive into Crystal Rev, the game's final major update, the design philosophy behind its scoring and difficulty, the influence of Cave classics like Ketsui and DoDonPachi, the importance of story in shmups, and what it's really like trying to make a living developing games in one of gaming's most niche genres.If you've played Emerald Blue, or you're curious about the people making the next generation of shmups, this is a conversation you won't want to miss.
