Welcome to your custom Desktop Companion! Here is exactly how to interact

with your new digital friend:

1. SELECTING YOUR COMPANION

* Choose from the 4 pre-made vector animals (Cat, Fox, Frog, Slime).

* Or, click 'Open Pixel Art Studio' to paint your own custom creation!

2. CONTROLLING YOUR PET

* LEFT-CLICK & HOLD anywhere on the animal to pick them up.

* DRAG your mouse to slide or fly them anywhere around your desktop.

* RELEASE the mouse button to drop them back onto your screen.

3. PIXEL ART STUDIO CONTROLS

* LEFT-CLICK & DRAG across the grid cells to paint with your active color.

* RIGHT-CLICK & DRAG across the grid cells to erase pixels back to blank space.

* Select different colors from the top palette bar.

* Click 'Spawn! 🚀' when you are finished to release them onto your display.

4. TURNING THE PET OFF

* When it is time to work or clear your desktop, simply tap the LEFT ALT

or RIGHT ALT key on your keyboard. The process will close instantly.

Have fun letting your new companions explore your wallpaper hills!
