> how you can work as a neuroscientist and at the same time be an indie developer
Lots of indie devs do the nights/weekends thing while working a day job — mine just happened to be in a lab. I'm not in any active research projects and now consider myself more of a science communicator aka making science-based games.
So I highly encourage you to lean into what you love about biology! If you keep honing your game-making skills on the side, I'm sure you'll find something cool and unique to say about biology in the language of games.
