Ended up pressing F and 1 about a hundred times till B and 1 worked, then got something on screen. Then I died within a couple of seconds.
I can now confirm there is something other than the initial audio in the game, there is a map, a player sprite and a "King" sprite. There is also player movement, enemy movement and the player can die.
I understand that there was not enough time for you to "complete" the game, but it's not much of a game to expect us to jump through these steps to get there.
I would have liked to see more of the game as the pixel art looked pretty clean when I got there.
