Graphics are slick and very crisp, always a plus. The music and sound effects are really nice; overall the game has a unique and interesting audiovisual style throughout the menus and game. The gameplay makes heavy use of the multitouch functionality of the iPhone, in a way that few other games do. There are some issues with the gameplay, such as new planets spawning in directly behind an already existing planets that contribute to the difficulty of Eliss. The sheer speed and number of planets on screen make the game extremely difficult just a few levels in. For instance I have only beaten around 15 of the 25 levels. A side effect is that you can actually make use of a second player on the same iphone to help you manage incoming planets, despite there being no official 2-player mode. There isnt much included in the package such as leaderboards or multiple modes, but the core of this game is very enjoyable and well put together. Personally I think a few small content updates could really improve the value proposition of this game, but I can only hope the developers find some spare time. I highly recommend Eliss, but if you try the demo and dont like it, theres not much more here.
