Yes, that's a very good point. Indeed, creating a video game is not easy. That's why our team doing a lot to make the study process more understandable and convenient. For example, we use Construct 3 as a game engine. This allows our students to learn game development without deep knowledge of coding. Also, we prepared students worksheets (depends on student's age), dictionaries, color rating scales (to identify bottlenecks of the VG study program). Currently, we are about to create a video course to help them learn game development and game design in a more quick and convenient way.
IMPORTANT NOTE. On this stage of VG program, our main purpose isn't a game developing as it is in the traditional sense, but bring back to young survivors the confidence that they still have complete control of their life by developing game worlds and characters, and letting children feel themselves responsible creators. This isn't about getting something done. It's about process. From this point of view, a small challenge is a very useful thing, as it encourages kids to adopt a growth mindset and teach them to see failures as opportunities to learn, grow and do things differently next time.
Also, I would like to add that, some parents were asking our mentors something like: "Is it possible to get a finished game at the end of the course?". Actually, yes and no. No, because our students have very different tech background. They can work as a group of students, but not as a team of developers. That's why we teach them the basic knowledge of game development. After our course, they will be able to create their own game by themselves. Yes, because we are working on additional classes where a group of kids will be working on developing some particular game. We are form believers that in the nearest future, we will publish the very first game developed by our students on the VitaGames itch.io page.
