@xu_yanfeng，您好，欢迎来到 GDevelop 社区。
Is this software maintained by a team? I think GitHub code is updated very frequently
Yes, we’re currently a small team of professionals working actively on it!
You can see a small part of the activity Github.
I really want to know where the team’s income comes from. It must be a very difficult process to do this
Until a few months ago, there wasn’t any income (outside of people who subscribed) or a full dedicated team. The only main Dev was 4ian, and everyone else were just contributors like every other open source project.
4ian recently got funding to start a full team, and now Clem, Alex, and others have been brought on to build a main dev team.
Cool, it seems that it’s not easy all the way. I hope it will develop better and better in the future
