I am sorry this game is trash. 1. Setting always move on default, i tried putting on medium and it goes back on high. 2. I bought many things and none appear on van on inventory. I have feeling whoever made this game didn't test it or played itself.
I think calling it ‘trash’ is a bit unfair. I developed this game a long time ago. Back then, I didn’t know much about how to progress and develop a game. Now, we are working as a team and have a much better understanding of game development.
On another note, the settings resetting is a bug, and this is the first time we’ve received a report about it. Also, to be able to use the items in missions, you need to place them in the back of the van after adding them to your inventory.
Nevertheless, thank you for your feedback. We are working hard to make better games.
