DRACO is a 2D top-down scroller shooter game. The app starts off with a good animation about the back-story of the game. The graphics and the music fit well into the game. After the intro video, the player, for the first time, will enter his or her own name. After which the player picks their hardness, color of their dragon and after a brief introduction to the controls is shown, the user can start the game.
The rules are fairly simple - avoid the oncoming dragons/obstacles & their fire/shots. Tilt the device in in either direction to move your dragon (tilt iPhone to the right, the dragon moves to the right, etc.) and tap the screen to shoot.
