Encountered errors while building your game.: Check your logs and post them to the forums.
- Please describe what you have been doing. Be as specific as possible.
Your game could not be built, because one of your images is too large to be included.
Check your backgrounds and actors with large sprite sheets. (max_string_size reached)
One of your images (actor animations or backgrounds) is too big. Retrace your steps from the last added backgrounds or actor animations to determine the culprit.
Another thing you can do is to disable all scales except x1, under Settings > Settings > Advanced, then go to Tools > Game > Cleanup unused files.
