Does the game run on an actual Gameboy? No, it's only a windows game made to seem like a Gameboy game.

Why can't I go full screen? Due to some engine limitations, the game requires capturing a pixel perfect scale of the game to output proper images, which full screen does not guarantee.

The audio doesn't sound very Gameboy-like... All the audio (Music/Sounds) was made using LSDj, a music tracker that runs on real Gameboy hardware!

I'm lost, is there a guide?  Aside from information provided in the README file, there is no in-game guide. While many aspects of the game were streamlined to make it a more accessible, easier ride, it is not expected of you find everything the game has to offer.
A general rule of thumb is once you've removed an anchor, the way to progress is usually in the crossroads.
