When it comes to actual gameplay, Syder is impressive. The controls are smooth, and the addition of subtle gravitational pulls against your ship adds an element of realism (not that I know what it feels like to steer a real starship). The virtual directional pad on the left is adequately sensitive and the Special Weapon and Flip buttons are comfortably placed.
Some dedicated fans of side-scrolling shooters might be wondering what a Flip button is for. Well, that is the unique thing about Syder. The game actually scrolls both to the left and the right. This makes the game significantly more difficult, since enemies are swooping in and firing from all sides. This isn't necessarily a bad thing, though. In fact, I enjoy the unique challenge that this multidirectional gameplay offers. Your starship automatically fires continuously, so it's your job to simply point your ship at the baddies and evade their fire, no matter what direction they're coming from.
