How do I get the controls to work? WASD doesn't move the character, the arrow keys do, but A and D are the only keys that can be used for struggling, the arrow keys don't! I can't keep switching between sets of keys back and forth.
There is an option to remap the controls, but A and D are locked for struggle. So, if you wanted to, you could remap movement to WASD (I prefer up for jump myself).
You can indeed customise the controls in the main menu options screen. But sadly we hardcoded the struggle to be A and D for now, so my suggestion is to use (W)ASD for movement. Sorry! Maybe in the future we will rework the struggle system.
