I use Construct 2 in my university basic game design class. This year I am having the students make the classic games from history. We are beginning with Spacewar!, Computer Space and Pong. Then moving to Donkey Kong, Pac Man and Space Invaders. They will remake their own versions of games as well. I have a Super Meat Boy prototype from one student in the works. It would be great to have example of those game mechanics on the site. I will be making tutorials of how we build these games but for instance I would love to be able to find a way to make the black hole from Spacewar! or the opening animations from Donkey Kong.
