yes, inverted control would be really easy to do but for some reason I did not think about it
few hours before submitting the game I had decided to turn off most of colliders, to avoid a lot of stuck bugs and give a chance to player to finish game's story.
I have plans to restore fuel on the island with a blue house, to avoid players go away of the map, but in the last moment feels lack of time to test it and just turned off menus on the island and made infinite fuel.
Yay!
You finish it to the end!
Thx for playing my game :)
