I played your game and it was a lot of fun with some tough financial questions that made me think. I did not find any major bugs, except that I was unable to get some of the upgrades as I ran out of questions before they were unlocked. Also you 800 x 600 issue should be possible to fix especially since you used Godot. Just go to project settings -> Display window and adjust some of those until it fits the guidlines. I hope this helps loved your game graphics as well.
