How many chapters are there going to be?
Radiant will have a minimum of 20 chapters, which should end up being around 30 hours of gameplay. Polarity will have around 11-12 chapters, closer to 15 hours.
Once Polarity is complete I will focus primarily on Radiant, with a small side-project that I will work on solo. However, when Radiant is done, I will start my next big project/continue to make games well into the future.
