Hey, everybody!
We've been following your feedback, and just pushed an update that should allow you to rebind your controls to whatever you desire.
This should also allow you to bind any controllers that weren't being properly recognized before!
Sorry for lacking this feature out of the gate. We made this little game in just a few days as a little Devolver treat, and ended up missing a few critical things!
I hope that all of you who weren't able to play can now enjoy a little mountain profiteering.
