I am quite confused, because there seems to be no way to go into full screen? In the settings, it says full screen, but there is no way to select it, and it is greyed out. Also, why are there so little resolution options? And why are they so odd?

I have three options to choose from,
1280x768
1280x800
1440x900

I really have no idea why this is, it is really odd though. I would like for the game to cover my entire screen, but because there is no way to select the full screen option, and with there not being a resolution option close to my monitors resolution, the game is taking up half of my screen. I mean, literally half. It's a strip cover half of my monitor vertically, but fits perfectly horizontally.

Speaking honestly, they kinda just threw this game out there to earn money asap but they plan to eventually add more graphic options to the menu so you'll have to wait it out a bit longer or somehow trick the thing into doing what you want. (don't ask me how I don't know since I don't mess with the graphic settings at all atm.)
