Thanks very much!  All working as described - love it so far.

Double-clicking after download just opens the zip file.  I had to Add Extension in Aseprite - if that's what you mean my double-clicking...

Thanks again.

SOLVED:  Just purchased and put in Aseprite (v1.2.40-dev) scripts folder.  When I try to run the script it says: Cannot open aseprite/extensions/the-tween-machine/lib/cc_utils.lua: No such file or directory.

I was putting the individual files in the scripts folder whereas I need to activate using the zip from from Preferences->Extensions.

Sorry - false alarm
