So I found my way to the "Treasure Adventure Game" website the other day, and I found out about this free online Unity course by Walker Boys Studio. So far it's really great! I just finished the first lesson and exam, which consisted of about 60 videos explaining the ins and outs of the software + some practice time. The exam was mostly multiple choice, some matching, etc to check if I had a grasp of the basics.
I'm particularly excited about the course because it's designed to take a novice scripter to a 'confident' one in Java. I'm looking forward to digging into it!
