Breakpoints probably wouldn't be much use as it's crashing just clicking the event sheet.
zenox98 Lol, yip, I completely missed read it, I did re-edit obviously whilst you were typing.
Another issue could be all those text boxes - text boxes are bad spritefont is good. lol
My best guess, is it is a little bit of a coding mess in there - lol.
3000 unique images - wow.
1 event sheet
and only 39.6mb download size and 65.7 memory use. Scratches head. Hard one to pin point.
1 event sheet is a no no,
You need a main event sheet that includes various sections (that you can then disable for bug testing etc)
