NyaHaX'93 is clear how much of the stage in 3 minutes, compete with or be acquired how much score, a time trial shooting game.
Instead there is no limit to the stock of its own equipment, penalty to receive the enemy of the bullets hit the "remaining time is reduced 10 seconds", two points of "stage again." Until anyway went 3 minutes, you can continue the game even if no matter what. Also the automatic fire mode is available, happy friendly design for beginners. Fairy-tale enemy characters and nimble BGM also, to have helped to soften the atmosphere of the prone shooting game becomes tasteless, it's a fun play 1 installment even without a shooting mania
