Though searching the web I found a number of tutorials for making games using Scratch. As I had never used scratch before I looked for a very basic tutorial to begin with to understand the structure of the program.
I found this helpful as a starting point. Scratch Basic
I then went on the search for videos on what games that can be created in scratch and how to complete them. I found the below video on describing the coding behind the simple Pacman example that is provided in scratch very useful.
I have yet to complete a game as it seems to be long process and I am deciding what I want it to be. I also found a video on creating a Pokemon game using scratch but after viewing a few tutorials I have come to the conclusion that it is too involved and time consuming to complete for this short homework assignment.
