I gave a look and I haven't seen anything that could cause this error :/
I suppose that the game was working by the past, right?
If yes, what have you done before the error appears ?
Did you have 7 layouts by the past? (i've seen in your events "Go to layout 7") and your event sheet 3 name is Layout 7 events
Yeah, this is a copy of the original. At first when I tried to put the .cap on here it was slightly too big (3.73 MB) So I made the copy and got rid of the other layouts other than the title, controls and the last layout that I was working on with the elevator. I guess now that I have the mediafire account I should post the full version. So here's that: mediafire.com/?4bgswk467df4ffi
