This game says it has full support for controller, but I can't find any button that function as space key and this make this game unplayable while using controller. Does anyone know how to deal with it, or any way to edit the controller bind?

I started playing and got stuck by a bug. When I restarted, the option to continue was grayed-out. How can I save so I can continue later?

Is the ost original? or royalty free?

I loved the concept and that ending really gives a dark, apocalyptic twist to the game! Good job :D https://www.youtube.com/watch?v=xcTxM4Z38yU

No big deal but while fighting the boss who chucks boulders at you, I was stuck in the right corner of the screen / could not move. :)
