only two weapons at their disposal: the main gun that travels a max distance of the screen's height and three bombs capable of obliterating any enemy caught within its blast radius. A unique gameplay feature is the weapon system; As enemies are destroyed, players gain experience points that are separate from the score and for every experience points gained, the main gun is leveled up and becomes much stronger. This is analogous to exp and levelling up in role-playing games. The weapon can only level up twice and after achieving its maximum level, experience points will grant players an extra bomb stock instead. In addition, player can also grab "P" icons to increase the power of the current level gun. A maximum of five "P" icons can be collected per experience level and getting more after this gives extra points instead, while collecting "B" icons increases the number of bomb stock to a maximum of seven. Another gameplay feature, reminiscent of Aero Fighters, is the ability to choose between three fighter ship variations: Sky Mirage (type A), Dragon's Whisper (type B) and Judgement Flasher (type C). Type A ships have a simple array of rapid-fire energy-beams that spread evenly. Type B ships shoot a straight beam of lightning for as long as the fire button is held, while tapping the button causes sparks to appear and travel along the beam. Lastly, Type C ships are adaptable; holding the fire button shoot energy waves straight, while tapping the button fires a spread of projectiles. Each ship type becomes more powerful by leveling up. There are multiple scoring methods for reaching high-scores to obtain extra lives in the game apart from destroying enemies, which are awarded at one million points. Points can be gained from collecting V-shaped gold medals and once the level is finished, points are awarded for every type of medal collected. Firing or bombing on determined locations is also crucial to reach high-scores, as certain setpieces in some stages hosts bonus secrets within their scenery, as well as destroying enemies on certain spots. The game employs a respawn system where a downed single player will start off immediately at the location they died at. Getting hit by enemy fire will result in losing a life, as well as a penalty of decreasing the ship's firepower to its original state, in addition of all medals collected and once all lives
