It's a well thought out game, but the mobile controls are a bit difficult. Personally, I use a mobile device at nights, not wanting to have too big of a screen to stare at. The icons are a bit too small, and the small moving pad, could be turned into a joystick. It's a more easy and sufficient way to move. The game is also a bit laggy. It's quite slow, and stiff feeling. But the game itself is a well, interesting, and fun game.
