The graphics were lifted straight from the arcade version, but the HUD was restricted to a simple vitality bar – the score and number of lives were displayed prior to starting the level. The sound was modified slightly to adapt it to the more limited audio hardware. The graphics were brighter. The controls were modified slightly to make it possible to only perform a high jump when the run button was pressed, whereas it was possible in the arcade version to perform one simply by being in motion when the jump button was pressed.
