1 month ago After leaving the game running for about 2 hours, I was able to observe similar slowdown in Flash Player. So I guess we're not necessarily doing anything wrong, but something is just very unoptimized in Ruffle compared to Flash Player.

Describe the bug
Link to SWF: http://i.notdoppler.com/files/grapplecat.swf
Grapple Cat works fine at first, but after a few minutes of gameplay its performance degrades significantly, making it just about impossible to play. This actually happens even if you lose the game and sit idle on the "game over" screen for a while. Here is what that looks like (notice the extremely low framerate):

Clicking the "Play Again" button returns the game to a normal framerate, probably because starting a new game destroys the objects that had accumulated.
Expected behavior
The framerate should remain acceptable during a reasonable gameplay session.
