Bangai-O

Arcade shooter. Very interesting mechanics of the game - your robot obeys the laws of gravity, so you need to constantly keep it in the air including the engines. You need to move and shoot from enemies in 8 directions. Different buttons are responsible for the directions of movement and shooting, so it is very difficult to play without a gamepad. There are 2 shooting modes:
Riki does more damage, Mami's are aimed by themselves after colliding with a wall. The original was only released in Japan, with a print run of 10,000 cartridges. A reworked version was later released for the Dreamcast.
