Hi,
I have opened an old project and I noticed that a graphic element coming from and SWF is no more correct as it was months ago:
FLASH original MovieClip
HTML5 representation
You can notice some elements have a wrong scale: a connection is flipped, and various pipes are too long. It looks like the scale parameter has been reset. I fixed the problem by re-exporting the SWF and setting the specific elements as bitmaps, but the SWF library needs a fix, as the old version I used to test the game months ago was ok.
