The pixel art is great! but I agree with previous comments, it would be great if you can remap the controls.
Thanks ! About the control remap : the fact that we split the control across the keyboard or between the joystick, can't be otherwise. We know it's weird and not friendly, it was not intented to be in a way, because the main goal of this setting was to share 1 controler for two people, as the two souls share 1 body to survive together, in order to incarnate the hybridization. If you have the opportunity, hybrid and synched yourself with another one to play it, I can guarantee you it will be fun ! (you might end up killing each other too indeed ;) )
