Bubble Bobble

This adorable and addictive action-platformer casts you as the twin bubble-blowing dragons, Bub and Bob, on a quest to rescue their kidnapped girlfriends from the Cave of Monsters. Across 100 single-screen levels, your goal is to trap every enemy in a bubble—blown from your mouth—and then pop the bubbles before the monsters can escape. The bubbles aren’t just weapons; they can also be used as temporary, bouncy platforms to reach higher ground, adding a clever puzzle element to the quick-paced action. Featuring charming graphics, an infamously catchy theme song that never leaves your head, and a simultaneous two-player co-op mode that makes the frantic gameplay even more fun, this is a timeless NES classic that combines simplicity with a surprising amount of depth and hidden secrets.
