If you haven’t already, try clicking a mouse button in-game? Some games switch between gamepad and keyboard+mouse modes based on the last input they’ve seen, and don’t treat mouse movement (which might be very slight) as counting as a “mouse mode switching event”.




















Not exactly what you’re asking for, but Magarena is an open-source Magic: The Gathering clone.
