Hi! Thank you so much for trying our game. Mind if I ask what gamepad you were trying to use? So far people seem to have been able to use the gamepad on web mostly fine, and I'd love to look into it for future game jams.
As for the keyboard controls, sadly it's hard to get controls working that literally everyone will be able to work with, starting with whether players want to use arrow keys or wasd. Therefore we did built our key remapping system that allows you to rebind every single key, including the pause menu. I hope that helps!
