Thanks for checking in :) I'm still working on it, but it's a very slow process. When I made the initial version of this game, it took me hundreds of hours of work over a few months. I'd spend 12+ hours a day on it. It's taken a few years to find that many hours to put into development again since I started a new career since making the first few updates.
It'll probably just be 0.4 - it'll have way more new and updated content than past updates, but at the end of the day, it'll still be an update from 0.3, so 0.4 makes sense 🤷
