The game must work without any unusual peripherals (such as a touch screen) on Windows, so it will first need to support traditional mouse or track pad.
(I’d forgotten that track pads can have gestures and support multi touch, so I’ll add a bit to exclude those.)
In addition to the mouse support, you may also include touch support, provided it doesn’t do anything without an equivalent mouse control (such as multi touch). I’ll add this to the jam page for clarification soon.
