Pursuit of Hat: level 5 does not load

[n0samu]

Describe the bug

Pursuit of Hat (an AS3 game) plays fine (with minor issues) until level 5, which refuses to load. Clicking the level just goes to a black screen.

Note: level 1 may not be playable the first time it is loaded. The same issue occurs in real Flash Player. Just go back to the level select screen and select level 1 again, and it should work.

There are also some minor issues with the game in Ruffle:

• You need to click inside each level to activate the keyboard controls.
• Restarting a level does not play the associated sound effect.
• The BigDino intro animation is skipped, though its audio plays.

Expected behavior

Level 5 should load, keyboard controls work immediately after loading a level, restarting a level should play the associated sound effect, and the BigDino intro should play.

Additional information

Here are the console log messages generated after clicking level 5 on the level select screen:
