The first thing I learned is that many of my classmates have terrible handwriting.
Kidding. More seriously, the feedback framed my vandalism cairn in a way I hadn’t expected while I was implementing it at 3AM right before the deadline. For one, many people referred to it as a game even though I hadn’t fully intended for it to be a game. People also emphasized the collaborative aspect much more than I had actually thought about during implementation. I also received useful execution feedback, such as technical things to fix, usability improvements, and further exploration of this idea.
