Highly amusing concept, I played to the end, though have to mention the Gameboy resolution requirement isn't met, and there is technically some extra inputs (you can use tab to cycle through UI elements, and the title screen reacts to mouse). Still, cool game!

I mean the UI elements aren't the same resolution as the pixel art behind it. It seems the game window itself is larger than 160x144, even though you have a viewport at the correct resolution stretched to fit. For example, the money counter is much higher resolution than Mr Holden Gold, it would be using a pixel font with the same sized pixels as him.
