A Key Sacrifice

You have discovered an old arcade-style game on your grandpa’s old computer. You are determined to get a high score, but the keyboard is very old with not much life left in it. You must sacrifice the keys to get a higher score, and will need to remap new keys for moving and shooting. How high of a score can you get before you either die or have no more keys to use?

Controls: WASD to move and arrow keys to shoot (initially). Spacebar to use a bomb.
