CTRL-Z, CTRL-Y (or S,F) to undo/redo
CTRL-C, CTRL-V to copy and paste between doodles
W,R to switch between doodles (or use the menu buttons)
TAB to toggle menu
Mouse wheel (or e,d) to change brush size
RMB to pick up a colour
RMB in menu colour palette to select secondary colour (used for patterns)
LMB+RMB in menu colour palette to set the background colour

Wobblepaint saves data to itself. To start a new wobble cart, type LOAD #WOBBLEPAINT from inside PICO-8 and then save it as something. The data storage is reasonably efficient so you can get around 20~100 doodles to a cart depending on complexity.
To save a gif to desktop, use the gif button to record a second of looping wobble. If you want to record multiple doodles (e.g. for an animation or story), press tab to hide menu, CTRL-8 to start a gif, W,R to flip through the doodles, and then CTRL-9 to save the gif."
