Noiz2sa is an abstract shoot them up written by Kenta Cho.
In this typical manic shooter, the ship must avoid bullets barrage and score as much as possible by destroying all enemies. It can safely touch any enemy or bullet as long as its core is not in contact with them.
More information available in the online manual.
