The Pocket Arcade:
Note differences in graphics, different stage two boss for example, more dots on the R-Zone version’s radar (three verses two), different life bar locations and more bars on the R-Zone (six verses three) version. The R-Zone background movement graphic for level two indicates a cave in the Pocket Arcade the same blocks are used every level. The countdown is continually shown on the R-Zone except briefly after defeating an enemy, the countdown is only shown for the last ten seconds in the Pocket Arcade. There is a dodging graphic in the R-Zone but nothing like that in the Pocket Arcade.
