Does this game run in full screen?
The game was originally designed to be a vertical oriented game (inspired by vertical shoot-em-ups), problem is monitors are landscape. So my game makes use of a dynamic background to square it out, and a static monitor image to fill the rest. It does help sell the mood besides cover a technical issue.
The main problem with scaling the game map itself is it would fundamentally change the gameplay and break many things. Give it a play, you'll see what I mean. If you like action games that is, I understand they're not for everyone
