I made a very simple tool without any documentation just for myself
to draw more faster some sprite animations by Tic-80 for Mosi.

I made a very bad tool because in Tic-80 not so easy to copy from log
and there's not an easy way to save to Text files,
but  I haven't any ideas how to make sprite editor in other tools.
I just made it for the current Bitsy Jam.

PS Happy XMas!
