Astral Chain ended up being a hit for PlatinumGames, selling over a million units. It's not easy to make a brand-new IP, and certainly equally as hard to have it be a sales success. Thankfully players were more than willing to check out the unique experience, which will hopefully lead to new installments down the road.
Seeing that success was very much welcomed by Takahisa Taura, the director of the game. In an interview with Famitsu, Taura talked about how stressful development was, and how Platinum's Hideki Kamiya stepped in to help out. Check out the snippet below, as translated by NintendoEverything.
For example, during development when something didn’t turn out to my absolute liking, I really started to panic. Kamiya really gave me his shoulder to lean on when that happened, but I don’t think I’ve ever felt a sense of distress like that before. ...That was when we were trying to nail down the action mechanics. Kamiya gathered all the things we had tried and tossed out or forgot about, and piece by piece it turned into something really great.
