early test build ALSO has controller support, witch is INSANE! but sugary spire doesn't have controller support
actually sugary spire DOES have controller support
but only with the xbox one
so to put playstation controller support into ss
just put ss into steam
and after that
launch ss and click "Shift + Tab" and activate steam input or whatever it is called
and after this
click the "returning" button on your playstation or whatever controller u have
and there you go
a good gameplay with a controller on ss
hope that helped :D
