This is a work in progress. It has been a pleasure working with Yang because he’s not afraid of a little challenge and will work hard to understand things that are not familiar to him. From the challenges we encountered, we learned a lot about programming from each other. Most of the challenges pertained to dealing with objects and functions.
Please check out this video clip! Next week, there will be a timer, and some other “game like” elements added. I really want to stick with this for my midterm because it will allow me to “K.I.S.S” but could be extended in many ways which will allow me to learn and practice key concepts of programming.
