I'm not an expert in löve, any tip would be great
Some of the controls:
Ctrl + left or right arrow = change frame
Ctrl + A = add frame (at last)
Ctrl + R = Remove actual frame
G = show/hide grid
shift + draw = eraser
in the save page there's a pseudo-textfield, it doesn't work perfectly.
I'll be updating the .love file in dropbox.
