I really enjoyed this course; I was able to make my own changes and improve on things like using interfaces to replace casting and implementing the enhanced interface system. I like these shorter courses; it gives me a taste of actually making a game without being bogged down with a lot of details (which is okay later on but for now I want to see a game to completion without spending a lot of time doing it.) I would give this course 5 stars, but I don’t know how at this site.
