Bolt is a fantastic tool for visual coding, which some people including myself find easier to absorb and enables you to see your code in action. It is also a great introduction/addition to learn coding.
Bolt has a very active discord channel with well over a thousand users and the developer is constantly working on improvements and features which sound very promising.
The only thing lacking are in depth tutorials and I feel gamedev.tv would make the best course. This could also bring in more customers for your other courses as I’m sure the rest of the bolt community would be interested and then buy your other courses in unity and blender.
Thanks
