Scirra is running a fun competition for users to upload the best video showing off Construct 2's features. While I'm sure the contest was designed to get more people to come across the program, its become a great way for people to learn how to use the program. I saw this video on Youtube that shows the power of Construct 2's layers and parallax scrolling. The real strength of it is how easy it is to set up. See for yourself.
