I'm an uber n00b and am attempting to follow some tutorials to teach myself this program. I've been following along with and it seemed to be going well, but all my blocks vanish upon drop. I can't figure out what I'm missing. Anyone willing to look over the files and tell me what I've messed up? I've started the tutorial over twice now, and keep getting the same result.
EDIT: ...okay, so apparent I can't use URLS. I'm on the 3rd page of the "Make a Match-3 Game in Construct 2" tutorial, first result in Google. Attached the file for download.
