Bubble Bobble

Gameplay involves jumping and collecting items like fruit for points, as well as using bubbles to trap enemies or create platforms for Bub and Bob to jump on. When an enemy is trapped in a bubble, popping it turns them into fruit, while power-ups floating in bubbles grant temporary advantages such as lightning that strikes horizontally at enemies or water that drags players and enemies downwards. However, if you take too long to complete a level, Baron Von Blubba will appear, attempting to destroy the player.

The original release on Amiga saw 40 levels, but the NES version added a few extra stages, bringing the total to 112 stages. Meanwhile, the Sharp X68000 version includes a hidden minigame called Sybubblun, featuring 20 original difficult levels with a unique Syvalion theme.
