Maroc's speed is increased/decreased in steps of 8 when keys are pressed. If the value is negative (value is > 128), Maroc is moving right. If the value is 0, Maroc is not moving horizontally, though he may be moving vertically.
A max speed of 32/-32 equates to Maroc moving 8 pixels per game cycle.

| 59499 | ADD A,D | Add the above to Maroc's speed accordingly | ||||||||
|
Speed can't be greater than 32 (or less than 224 if Maroc is moving right), so limit speed to this value if it's gone over.
