Press the green flag a few times to start the program and Start to start the game. Press A and D to move, and W and S to change Gravity. (W is upside-down and s is right-side up.) Avoid all red things except the health bar (In level 4 it's brown things, so ignore the lasers). I cannot tell you how to kill the boss, but I can tell you, "You have all of gravity on your side."
