thanks, what gamepad/controller were you using out of curiosity? I only tried with xbox360 controller which works with the left analogue stick mapped, I could map the D-pad on that also, maybe that would do it. Not sure if updating to add that now would breaks the rules though. Would be nice to support more traditional style input devices generally in the future though.
Just a generic-digital-USB gamepad, like this model for instance:
See? no brand on it, cheap and no analogue stick at all. :D
Better wait till the voting it's over, not sure if it's allowed to upload in-jam updates.
That will be not fair.
