Problems¶
Problems checks the whole game as you work and lists anything that would stop it working as you meant. Click a problem to jump to where you fix it.

The footer always shows the count, or No problems. With none, the tool says No problems found.
Errors and warnings¶
Errors (red) break the game: it may not start, or something will be missing. Warnings (amber) are probably not what you meant.
