Balloon Bomber

Balloon Bomber is a shoot 'em up arcade game released by Taito in 1980. You control a shooter that moves left and right and shoots balloons that drop bombs at you. If the bomb misses you, it makes a crater at which point you cannot move past, thereby limiting your movement to avoid bombs.
This game was re-released on 3 compilation games, including Taito Legends 2 for PlayStation 2 and Taito Memories Pocket (Japan/Asia) and Taito Legends Power Up (Europe) for PSP.
