Bubble Bobble, an arcade game released in 1986 by Taito. The game was originally released for Coin-Op, later converted to most home computers (including Amiga) and personal PC.
In the game we play two dragons named Buba and Bob. The aim of the game is to eliminate the creatures from the game. Your only weapon is the bubbles you release from the mouth. The bubbles in contact with the enemy, immobilize him and you can calmly enter into it and gain fruit (hence the points).
Bubble Bobble is a very addictive game - despite the simplicity. The fun is getting bigger and bigger in two player mode. The game contains 100 levels, which are interleaved with bonus stages.
