Slingshot Pilot has been developed with the Steam Deck as the main device for dev.
The Deck is a suprisingly complete linux development environment and allows for fast and comfortable development, when docked to a regular USB-C to use keyboard, mouse and an external screen.

The Acer PC you see in the image is just my "cross-plattform" test device for windows..

It's been a blast so far. And working directly on the Deck helped design specifically for it,
maximizing compatibility. I am sure you will have as much fun playing Slingshot Pilot on the Deck as I had developing it!
