I have a problem with the game Inferno+, and seeing the developer has no contact details on the home page but the various indie bundles have a certain popularity here, I though I'd get a solution here.

So, my problem is that the game only seems to recognize horizontal movement on the right stick of my dual stick gamepad (a Saitek P480 Rumble Pad). Checking in Windows' Game Controllers panel, the right stick is also functioning correctly, so the problem isn't in my gamepad.
I've also checked the gamepad tester application offered on the game's page and it also recognized every movement of the right stick. It's as if only the game itself didn't.
EDIT: Just to be sure, I also tried the registry fix offered there, but that only made the game not recognize my sticks at all.

Do you have an idea regarding what could I do with this issue? Or, if not, can someone tell me how I can get in touch with the developer (aside from FB and Twitter)?

Never mind, it seems one of the axes for firing wasn't configured well. I've reconfigured it, and now it is working.
