Considering Alex's response in regards to Extends not being remembered for player 1 I consider that a good enough reason to allow the insertion of 2 credits to allow player 2 to be used.(posted 9590 days ago)As regards the gaining of frequent extends that is up to the player to encourage by wasting as many enemies in one hit as possible in screens immediately prior to a screen with "holes" at the bottom for the extend letters to come through.
Well done Bubble on an impressive recording - I could only ever complete the C=64 version that had a nice bug of being able to trap the enemy through a solid wall from the left side of the wall.
