Wow thanks! I'm glad you really enjoyed it :)
Yeah I'm happy to give you permission to make changes and host it on the puzzle script gallery, I'd be quite honoured actually.
I originally made this in puzzle script so most of the code I think would work. One patch I did was with 'once' to ensure the pipe splash sound plays once instead of 2-4 at the same time, but that hopefully is a small tweak as well.
Let me know if there's anything you need to help out.
