Learned well initially. The template worked on in this course became my foundational framework. I extracted needed parts myself, made a template repository, providing the productivity to build games as if mass-produced. I completed 22/91 lessons. After 10 hours, the moment the instructor put down M1, I also dropped the course. It's not that I didn't hear the part about collaborative development with other companies. Watching it, a sigh just came out naturally. It's a truly difficult part. Seeing him cleaning up trash in a course I hoped would build things up was simply disappointing. However, I absolutely could not recommend it to friends studying together. I could recommend the instructor, but not this course. The reason I didn't get a refund was because of the instructor, not the course. Honestly, the "if you're upset, you're blocked" notice sent via email felt like the instructor crossed a line. However, conversely, I can't imagine how many complaints they received. Seeing the level of talk like "people who don't know the difficulties of the real world aren't qualified to listen," I honestly wonder, what is this? Does he want to do freelance work and make money? Does he want to make courses as a side job while developing? I also understand the risks of sharing real-world work. Passing that risk onto the students was just a laughing point. In the midst of that, the continuously expanding course was just a betrayal. The course wasn't finished to the point where one might think, "Isn't this crowdfunding fraud?" Finally, after 2 years, upon hearing news of completion using dwikkut, I'm leaving this review as part of an event. I think everyone will understand why it's difficult to give 5 points. It's a million-fold blessing that there hasn't been news of consumer complaints. It's not that the money for learning was a waste, it was just fun and bitter.
