Hello Fat Panda,
I tried to play the demo using the Logitech controller (Logitech F310) on Windows. At first, the movement works; but, buttons were not working.
Before I wrote this response, I did try to change the button mapping from the standard Unity menu.
There are like 6 'Fire', 2 'Right Dash' and 2 'Left Dash' inputs; also I couldn't guess which mapping works for 'God mode', 'sub-weapon' or the normal attack. Could Fat Panda guide us?
