by HardUserK.I is an excellent shmup that has more room for movement sideways than vertically, much like Capcom's Mars Matrix.
Unlike other shooters, your ship can take more than a few hits before going down. It's current health is shown on the upper left of the screen. Power-ups can be collected to upgrade your firepower or replenish the ship's energy level.
Both your bullet dodging and grazing skills will be tested here, because the only way to charge up your special weapon is by grazing enemy projectiles. Press the X key to activate it when the counter passes one hundred, else it won't work at all. Tap the same button twice to save it's energy while removing all enemy bullets from the screen.
